12. The simple random sample of the ages of the children entering a carnival yields the following results: ages 5, 7, 8, and 9 years old. A sample size of 3 are drawn form this. a. How many possible sample size of 2 are drawn from the population? b. List all the possible samples of size 3 can be drawn from the population, and make a sampling distribution of the sample means. c. Find the mean, variance, and standard deviation of the sampling distribution of the sample means.
