Consider a population consisting the scores of 8 students in a Statistic test.
18, 22. 25, 28, 32, 38
Suppose samples of size 3 are drawn from this population, describe the
sampling distribution of the sample means following the steps below:
1. What is the mean of the population?
Show your solutions here.
2. What is the variance of the population? Fill in the table and
show your solutions here.
(X - P)
(X - H) ?
3. Determine the number of possible samples of size 3
Show your solutions here.
