Question 2

When analyzing the performance of each division in your organization in regards to sales quotas, you would look at the standard deviation of each division to determine:
A)the mean performance of all divisions
B)how far apart the divisions are from the mean
C)what level of performance was most commonly occurring

Standard deviation measures the amount of variation or dispersion from the average (mean). Therefore, it helps in determining how far apart the divisions' performances are from the mean performance.

Question 3

You are analyzing the relationship between employees working more than ten hours in a shift and the number of on the job accidents at your production facility. One aspect to consider is the relative frequency which would be:
A)the total number of accidents divided by the number of times employees worked more than ten hours in a shift
B)the number of times employees worked more than ten hours in a shift divided by the total number of accidents
C)the number of times employees worked more than ten hours in a shift minus the total number of accidents divided by the number of times employees worked more than ten hours in a shift
D)The total number of accidents times the number of times employees worked more than ten hours in a shift divided by the total number of accidents.

Accepted Answer

Relative frequency in this context refers to how often accidents occur in relation to the number of times employees worked more than ten hours. Thus, it's calculated by dividing the total number of accidents by the number of times employees worked more than ten hours in a shift.

Question 4

If asked to provide the quotient of your division's clocked work hours (Hours) and the number of division employees (Employees), the answer would be calculated by which of the following formulas?

B)were better than 90% of the candidates tested
C)demonstrated exceptional proficiency in computer applications

Question 7

If simple interest is calculated using the formula A=P(1+nr) where A is total principle and interest, P is principle, n is number of years, and r is rate, what would be the simple interest earned on an investment of $2000.00 at 12.5% for 9 years?
A)$4,250.00
B)$2,250.00
C)$1,250.00
D)$250.00

Accepted Answer

The simple interest can be calculated using the formula for total amount A = P(1 + nr), where P = $2000, n = 9 years, and r = 12.5% or 0.125. Plugging these values in, A = $2000(1 + 9*0.125) = $2000(1 + 1.125) = $2000 * 2.125 = $4250. The interest earned is the total amount minus the principal, so interest = $4250 - $2000 = $2250.
