The average number of employees that call in sick for the day over the course of a year is 25.

the number of employees that call in sick on 12 days are

25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28, and 14.

enter the sample mean and the population mean.

i) sample mean; 24

ii) Population mean; 25

Step-by-step explanation:

i)

We are given the following sample data of the number of employees that call in sick on 12 days;

25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28, and 14.

The sample mean is simply the average value of a sample data. To find the average, we simply find the sum of the values and divide the result by the number of values in the given sample;

The sum of the above values is; 288

The number of values is; 12

The sample mean is thus ; x¯ = 288/12 = 24

ii)

The population mean is the average value of a population data and is one of the characteristics of a population that is usually not known. In statistics, this is referred to as a Parameter.

We have been informed that the average number of employees that call in sick for the day over the course of a year is 25. Therefore, the population mean μ is 25.
