Answer to Question #54995 in Statistics and Probability for skeeter

Question

Suppose that the 25
even-numbered students among the 50 students available
for the comparison of classroom and online instruction
(Example 9.5) are older, employed students. We hope that
randomization will distribute these students roughly equally
between the classroom and online groups. Use the Simple
Random Sample applet to take 20 samples of size 25 from the
50 students. These 25 students will be the classroom instruction
group. (Be sure to click “Reset” after each sample.) Record the
counts of even-numbered students in each of your 20 samples.
(a) How many older students would you expect to see in the
classroom instruction group?
