Question

For the following situation, find the mean and standard deviation of the population. List all samples(with replacement) of the given size from that population. Find the mean and standard deviation of the sampling distribution and compare them with the mean and standard deviation of the population. The number of DVDs rented by each of three families in the past month is 6,11,and 4. Use a sample size of 2.

The mean of the population is?

The standard deviation of the population is?

Mean of the population = 21/3 = 7

Standard deviation of population
