Consider this population data set: 4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. the values 11, 31, 22, and 12 constitute a random sample drawn from the data set. the sample mean is more than the population mean by a. 3.5 b. 15.5 c. 19 d 110

The correct option is A.

Step-by-step explanation:

The formula for mean is

The population data set is:

4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, 12

The population mean is

The sample data set is

11, 31, 22, 12

Difference between population mean and sample mean is

The sample mean is more than the population mean by 3.5.

Therefore the correct option is A.
