Question

Suppose that for a graduating class of seniors at a local high school, the average GPA is 3.21. If a sampling distribution of size n = 20 is created from this population of seniors, what would be the expected mean of the sampling distribution?

Answer 1

The expected mean of the sampling distribution of size n = 20 from a graduating class with an average GPA of 3.21 is also 3.21.

Step-by-step explanation:

The question asks about the expected mean of a sampling distribution created from the population of seniors with an average GPA of 3.21.

When a sampling distribution is created, the expected mean of the sampling distribution, also known as the sampling distribution of the sample mean, is equal to the population mean.

Therefore, for a sample size of n = 20, the expected mean of the sampling distribution would simply be the same as the population mean, which is 3.21.
