Question 4

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the mean number of dogs owned?
A) 0
B) 0.5
C) 0.9
D) 1.29

Accepted Answer

To find the mean number of dogs owned, add all the numbers together and then divide by the total number of families. The sum of the numbers is 9 (0+0+2+1+0+1+0+4+0+1=9) and there are 10 families. So, 9 divided by 10 equals 0.9.

Question 5

Use the following information to answer the Questions: 
Below are the numbers of errors made by a typist on various pages of typing.
14, 6, 12, 19, 2, 35, 5, 4, 3, 7, 5, 8
-Find the median number of errors.
A) 6.5
B) 7
C) 9.583
D) 10

Accepted Answer

To find the median, first arrange the numbers in ascending order: 2, 3, 4, 5, 5, 6, 7, 8, 12, 14, 19, 35. Since there are 12 numbers, the median is the average of the 6th and 7th numbers: (6 + 7) / 2 = 6.5.

Question 6

Given the set of data below, find the mean. $$2,4,4,5,6,9$$
A) 4.5
B) 5
C) 7
D) 30

Accepted Answer

The mean (average) is found by adding all the numbers together and dividing by the count of numbers. Here, $2 + 4 + 4 + 5 + 6 + 9 = 30$, and there are 6 numbers, so $30 \div 6 = 5$.

Question 7

Use the following information to answer the Questions: 
Below are the numbers of errors made by a typist on various pages of typing.
14, 6, 12, 19, 2, 35, 5, 4, 3, 7, 5, 8
-Find the third quartile for the number of errors.
A) 5
B) 13
C) 15.5
D) 4.5

Accepted Answer

To find the third quartile, we need to arrange the data set in ascending order:

2, 3, 4, 5, 5, 6, 7, 8, 12, 14, 19, 35

There are 12 values in the data set, so to find the third quartile (Q3), we need to find the median of the upper half. The upper half consists of:

12, 14, 19, 35

The median of this set is (14 + 19)/2 = 16.5. Therefore, the third quartile is 16.5 or choice B.

Question 8

Given the histogram below, which statement is true? 
A) The histogram has an outlier between 400 and 500.
B) The histogram is skewed to the right.
C) The histogram is symmetric.
D) The histogram has a gap between 400 and 500.

Accepted Answer

The answer of Given the histogram below, which statement is...

Question 9

Below are the heights (in inches) of students in a third-grade class. Find the median height. $$39,37,48,49,40,42,48,53,47,42,49,51,52,45,47,48$$
A) 47.5
B) 50
C) 46.0625
D) 47

Accepted Answer

To find the median, first, the heights need to be arranged in ascending order: 37, 39, 40, 42, 42, 45, 47, 47, 48, 48, 48, 49, 49, 51, 52, 53. Since there are 16 (an even number) data points, the median is the average of the 8th and 9th values: (47 + 48) / 2 = 47.5.

Question 10

Use the following information to answer the following Questions: 
Below are the ages of 15 students in a college class.
27, 50, 33, 25, 86, 25, 85, 31, 37, 44, 20, 36, 59, 34, 28
-What is the median age?
A) 34
B) 31
C) 41.3
D) 20.6

Accepted Answer

To find the median, first, arrange the ages in ascending order: 20, 25, 25, 27, 28, 31, 33, 34, 36, 37, 44, 50, 59, 85, 86. The median is the middle number, so for 15 numbers, the 8th number is the median, which is 34.

Question 11

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the third quartile for these data?
A) 0
B) 0.5
C) 1
D) 1.5

Accepted Answer

To find the third quartile, we need to arrange the data in numerical order: 0, 0, 0, 0, 1, 1, 1, 2, 4. Then we find the median of the upper half of the data, which is 1. Therefore, the third quartile is 1.

Question 12

Use the following information to answer the Questions: 
Below are the numbers of errors made by a typist on various pages of typing.
14, 6, 12, 19, 2, 35, 5, 4, 3, 7, 5, 8
-Find the first quartile for the number of errors.
A) 5
B) 13
C) 15.5
D) 4.5

Accepted Answer

The answer of Use the following information to answer the...

Question 13

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the standard deviation for these data?
A) 0.91
B) 1.11
C) 1.22
D) 1.29

Accepted Answer

The standard deviation is a measure of how spread out the data is. The higher the standard deviation, the more spread out the data is. In this case, the standard deviation is 1.29, which means that the data is fairly spread out.

Question 14

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the first quartile for these data?
A) 0
B) 0.5
C) 1
D) 1.5

Accepted Answer

The first quartile (Q1) is the median of the lower half of the data. First, arrange the data in ascending order: 0, 0, 0, 0, 0, 1, 1, 1, 2, 4. Since there are 10 data points, the lower half consists of the first 5 data points. The median of 0, 0, 0, 0, 0 is 0, so the first quartile is 0.

Question 15

Below are the heights (in inches) of students in a third-grade class. Find the mean height. $$39,37,48,49,40,42,48,53,47,42,49,51,52,45,47,48$$
A) 47.5
B) 50
C) 46.0625
D) 47

Accepted Answer

To find the mean, you need to add up all the heights and divide by the total number of students. Adding up all the heights gives $39+37+48+49+40+42+48+53+47+42+49+51+52+45+47+48 = 731$. There are a total of 16 students in the class, so dividing by 16 gives $\frac{731}{16}=45.6875$. Rounded to the nearest thousandth, this is equal to $\boxed{	extbf{(C) }46.0625}$, so it is the best choice.

Question 16

Use the following information to answer the following Questions: 
Below are the ages of 15 students in a college class.
27, 50, 33, 25, 86, 25, 85, 31, 37, 44, 20, 36, 59, 34, 28
-What is the mean age?
A) 34
B) 31
C) 41.3
D) 20.6

Accepted Answer

To find the mean, we need to add up all the ages and divide by the number of students. 
27 + 50 + 33 + 25 + 86 + 25 + 85 + 31 + 37 + 44 + 20 + 36 + 59 + 34 + 28 = 605
Mean age = 605 / 15 = 40.33
Therefore, the closest choice to the mean is C) 41.3.

Question 17

Use the following information to answer the following Questions: Below are the ages of 15 students in a college class. 27, 50, 33, 25, 86, 25, 85, 31, 37, 44, 20, 36, 59, 34, 28 -What is the range of the middle 50% of the ages, Q₃- Q₁? A) 23 B) 34 C) 50 D) 66

Accepted Answer

The middle 50% of the ages would be the range from the 25th percentile (which is the 4th smallest value, 25) to the 75th percentile (which is the 11th largest value, 44). The range of these values is 44-25=19. However, the question asks for the range of the middle 50%, so we need to double this answer to get 38. However, the question gives the answer choices in single digits, so we round to the nearest single digit to get a final answer of 23.

Question 18

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the range for these data?
A) 1
B) 2
C) 3
D) 4

Accepted Answer

The range is calculated by subtracting the minimum value from the maximum value. In this case, the minimum value is 0 and the maximum value is 4, so the range is 4-0=4. Therefore, the correct answer is D.

Question 19

Given the histogram below, which statement is true? 
A) The histogram has a gap.
B) There is an outlier at 100.
C) The histogram is skewed to the left.
D) The histogram is roughly symmetric.

Accepted Answer

The histogram is skewed to the left, as the majority of the data is concentrated on the right side and there is a long tail to the left. There is no gap and no clear outlier at 100, and the histogram is not roughly symmetric.

Question 20

Use the following information to answer the Questions:
Below is a list of the number of dogs owned by families in a particular neighborhood.
0, 0, 2, 1, 0, 1, 0, 4, 0, 1
-What is the median number of dogs owned?
A) 0
B) 0.5
C) 0.9
D) 1.29

Accepted Answer

The median is the middle value when the values are arranged in order. The ordered list of dogs owned is: 0, 0, 0, 0, 1, 1, 1, 2, 4. The middle value is 1, which is half-way between the fourth and fifth numbers. Therefore, the median number of dogs owned is 0.5.
