Question 1

Pinky Bauer,Chief Financial Officer of Harrison Haulers,Inc. ,suspects irregularities in the payroll system,and orders an inspection of "each and every payroll voucher issued since January 1,2013." Pinky is ordering a ___.
A)statistic from the payroll vouchers
B)census of the payroll vouchers
C)sample of the payroll vouchers
D)sorting of the payroll vouchers
E)parameter of the payroll vouchers

Accepted Answer

Pinky is ordering a complete count or census of all the payroll vouchers issued since January 1, 2013 to investigate suspected irregularities. A sample (C) would not provide enough information, sorting (D) is a process of arranging or categorizing data, and parameters (E) are characteristics of a population that are estimated using statistics.

Question 2

Interval- and ratio-level data are sometimes referred to as quantitative data.

Accepted Answer

Interval- and ratio-level data are both quantitative data types, which are numerical in nature and can be compared mathematically.

Question 3

Using data from a group to generalize to a larger group involves the use of ___.
A)descriptive statistics
B)inferential statistics
C)population derivation
D)sample persuasion
E)relative level data

Accepted Answer

Inferential statistics involves drawing conclusions about a population based on data from a sample. This is the process used to generalize findings from a smaller group to a larger population. Descriptive statistics describe the characteristics of the sample, but do not generalize to the larger population. Population derivation involves defining the characteristics of the entire population, which is often impossible to do. Sample persuasion and relative level data are not commonly used statistical concepts.

Question 5

Marc Fortier,Director of Human Resources,is exploring the causes of employee absenteeism at Lennoxville Bottling during the last operating year (January 1,2013 through December 31,2013).For this study the set of all employees who worked at Batesville Bottling during the last operating year is ___.
A)a parameter
B)a sample
C)the population
D)a statistic
E)the frame

Accepted Answer

The set of all employees who worked at Lennoxville Bottling during the last operating year is the entire population being studied.

Question 6

Manuel Banales,Marketing Director of Plano Power Plants,Inc.'s Electrical Division,is directing a study to identify and assess the relative importance of product features.Manuel directs his staff to design a survey questionnaire for distribution to 100 of Plano's 954 customers.For this study,the set of 100 customers is ___.
A)a parameter
B)a sample
C)the population
D)a statistic
E)the frame

Accepted Answer

The set of 100 customers is a sample because it is a subset of the larger population of Plano Power Plants, Inc.'s customers. A parameter refers to a characteristic of the entire population, while a statistic refers to a characteristic of the sample. A frame is the list of all individuals or objects in the population that could be included in the sample.

Question 7

On discovering an improperly adjusted drill press,Jack Joyner,Director of Quality Control,ordered an inspection of every fifth casting drilled during the evening shift.Jack is ordering a ___.
A)statistic from the castings
B)census of the castings
C)sample of the castings
D)sorting of the castings
E)parameter of the castings

Accepted Answer

Jack Joyner is taking a sample of the castings by inspecting every fifth casting drilled during the evening shift. This allows him to gather information about the quality of the castings without inspecting every single one, which would be a census. A statistic is a numerical summary of a sample or population, a sorting is a process of separating items into categories, and a parameter is a characteristic of a population.

Question 8

Manuel Banales,Marketing Director of Plano Power Plants,Inc.'s Electrical Division,is directing a study to identify and assess the relative importance of product features.Manuel directs his staff to design a survey questionnaire for distribution to all of Plano's 954 customers.For this study,the set of 954 customers is ___.
A)a parameter
B)a sample
C)the population
D)a statistic
E)the frame

Accepted Answer

The set of 954 customers represents the entire group of interest, so it is the population for this study. Parameters are characteristics of the population that are measured, whereas statistics are characteristics of a sample that are measured. Frames refer to the list of all individuals or organizations being studied, which may or may not be identical to the population. Thus, only C accurately describes the set of 954 customers in this context.

Question 9

Marc Fortier,Director of Human Resources,is exploring the causes of employee absenteeism at Lennoxville Bottling during the last operating year.Personnel records for 50 of the plant's 250 employees are selected for analysis.For this study,the group of 50 employees is a ___.
A)parameter
B)sample
C)population
D)statistic
E)frame

Accepted Answer

The group of 50 employees is a sample, as it represents a subset of the population (all 250 employees at the plant). A parameter refers to a characteristic of the population, a statistic refers to a characteristic of a sample, and a frame refers to a list of all items in a population.

Question 10

Sue Taylor,Director of Global Industrial Sales,is concerned by a deteriorating sales trend.Specifically,the number of customers is stable at 1,500,but they are purchasing less each year.She orders her staff to search for causes of the downward trend by surveying all 1,500 industrial customers.Sue is ordering a ___.
A)statistic from the industrial customers
B)census of the industrial customers
C)sample of the industrial customers
D)sorting of the industrial customers
E)parameter of the industrial customers

Accepted Answer

Sue is ordering a census because she is asking for information from every member of the population (all 1,500 industrial customers), not just a subset.

Question 11

When a person collects information from the entire population,this is called a ___.
A)parameter
B)sample
C)population
D)census
E)statistic

Accepted Answer

When a person collects information from the entire population, it is called a census. A parameter is a characteristic of a population, while a sample is a subset of a population. A population is the entire group being studied, and a statistic is a characteristic of a sample.

Question 12

Nominal and ordinal data are sometimes referred to as qualitative data.

Accepted Answer

Nominal and ordinal data are two types of qualitative data. Qualitative data is non-numerical data that describes qualities and characteristics.

Question 13

On discovering an improperly adjusted drill press,Jack Joyner,Director of Quality Control,ordered a 100% inspection of all castings drilled during the evening shift.Jack is ordering a ___.
A)statistic from the castings
B)census of the castings
C)sample of the castings
D)sorting of the castings
E)parameter of the castings

Accepted Answer

Jack is ordering a census, which is a 100% inspection of all castings. A statistic would involve analyzing a sample of the castings. A sample would involve inspecting only a portion of the castings. Sorting would involve separating the castings by some characteristic, such as size or defect. A parameter is a characteristic or value of the population being inspected, and is not relevant to the task at hand.

Question 14

With interval-level data,the zero point is a matter of convention and does not mean the absence of the phenomenon under observation.

Accepted Answer

Interval-level data is measured on a scale where the differences between values are known and meaningful, but the zero point does not indicate the complete absence of the phenomenon being measured. The zero point is arbitrary and is determined by convention rather than representing a true absence of the variable being measured.

Question 15

Sue Taylor,Director of Global Industrial Sales,is concerned by a deteriorating sales trend.Specifically,the number of customers is stable at 1,500,but they are purchasing less each year.She orders her staff to search for causes of the downward trend by selecting a focus group of 40 industrial customers.Sue is ordering a ___.
A)statistic from the industrial customers
B)census of the industrial customers
C)sample of the industrial customers
D)sorting of the industrial customers
E)parameter of the industrial customers

Accepted Answer

Sue Taylor is ordering a sample of the industrial customers, which is a subset of the total population of customers. She is not trying to survey every single customer (census) or sort them in any particular way. She is also not concerned with a specific numerical value (parameter) or a summary of data (statistic) at this point, but rather trying to understand the causes of the trend through a smaller group of customers.

Question 16

Manuel Banales,Marketing Director of Plano Power Plants,Inc.'s Electrical Division,is leading a study to identify and assess the relative importance of product features.Manuel directs his staff to design a survey questionnaire and distribute it 100 of Plano's 954 customers.Manuel is ordering a ___.
A)statistic from the customers
B)census of the customers
C)sample of the customers
D)sorting of the customers
E)parameter of the customers

Accepted Answer

Manuel is selecting a group of customers from the population of all Plano customers to survey. This is known as a sample. Option A is incorrect because Manuel is not looking for a single numerical value to represent the entire population. Option B is incorrect because a census would involve surveying the entire population, which Manuel is not doing. Option D is incorrect because Manuel is not sorting or categorizing the customers, he is surveying them. Option E is incorrect because a parameter is a numerical value that describes a population, not an individual or group within the population.

Question 17

Pinky Bauer,Chief Financial Officer of Harrison Haulers,Inc. ,suspects irregularities in the payroll system,and orders an inspection of "every tenth payroll voucher issued since January 1,2013." Pinky is ordering a ___.
A)statistic from the payroll vouchers
B)census of the payroll vouchers
C)sample of the payroll vouchers
D)sorting of the payroll vouchers
E)parameter of the payroll vouchers

Accepted Answer

Pinky is ordering a sample of the payroll vouchers, as she is selecting every tenth voucher to inspect. A statistic would be a numerical summary of data, which is not what Pinky is requesting. A census would be an investigation of every single member of a population, which would be impractical in this situation. A sorting would involve organizing the vouchers in a particular order, which does not address Pinky's suspicion of irregularities. A parameter is a characteristic of a population, and Pinky is not requesting information about the entire population of payroll vouchers.

Question 18

Nominal and ordinal data are sometimes referred to as quantitative data.

Accepted Answer

Nominal and ordinal data are actually types of categorical data, not quantitative. Quantitative data refers to numerical data that can be measured or counted.

Question 19

Sue Taylor,Director of Global Industrial Sales,is concerned by a deteriorating sales trend.Specifically,the number of industrial customers is stable at 1,500,but they are purchasing less each year.She orders her staff to search for causes of the downward trend by selecting a focus group of 40 industrial customers.For this study,the set of 40 industrial customers is ___.
A)a parameter
B)a sample
C)the population
D)a statistic
E)the frame

Accepted Answer

The set of 40 industrial customers is a sample because it is a subset of the larger population of 1,500 industrial customers. This sample is selected in order to draw conclusions and make inferences about the population.

Question 20

Sue Taylor,Director of Global Industrial Sales,is concerned by a deteriorating sales trend.Specifically,the number of industrial customers is stable at 1,500,but they are purchasing less each year.She orders her staff to search for causes of the downward trend by surveying all 1,500 industrial customers.For this study,the set of 1,500 industrial customers is ___.
A)a parameter
B)a sample
C)the population
D)a statistic
E)the frame

Accepted Answer

The set of 1,500 industrial customers represents the entire group of interest for the study, making it the population.
