Question

Suppose a population consists of the four numbers 2, 4, 6 and 8. Consider all random samples of size n that can be formed by sampling with replacement.

Hint: Consider the box below when we make n draws with replacement.

​

What is the sampling distribution of sample mean when n =25?

A) Approximately Normal [5, 0.48]

B) Approximately Normal [6, 0.49]

C) Approximately Normal [4, 0.49]

D) Approximately Normal [6, 0.24]

E) Approximately Normal [4, 0.24]

F) Approximately Normal [100, 150]

G) Approximately Normal [25, 0.33]

H) Approximately Normal [125, 0.24]

I) Approximately Normal [6, 0.48]

J) Approximately Normal [6, 0.24]

Hint: 1) The notation used: Normal [mean, SD]

2) Choose the best one.
