A population consists of the following five values: 2, 2, 4, 4, and 8.

a. Not available in Connect.

b. By listing all samples of size 2, compute the mean of the distribution of the sample mean and the population mean. Compare the two values.

Sample means = ?

Population mean= ?

Both means are equal not equal ?

c. Compare the dispersion in the population with that of the sample means. Hint: Use the range as measure of dispersion.

The dispersion for the population is greater or less than that for the sample means?
