Question

8. Many samples of 63 employees are taken from a population, and the average number of sick days taken by an employee per year is calculated for each sample. If the mean for the population is 4.1 sick days, what will be the approximate value of the mean of the sample means?

Answer choices:
4.1 sick days
4.5 sick days
4.9 sick days
5.3 sick days

Answer 1

The mean of the sample means will be equal to the population mean. Therefore, the answer is 4.1 sick days.

Explanation:

Assuming that the sample means are unbiased estimators of the population mean, the mean of the sample means will also be equal to the population mean. Therefore, the answer is 4.1 sick days.
