Finding the probability of sample and describe the sampling distribution of the sample means.

Identify the probability of sample, and describe the sampling distribution of the sample means. Personal phone calls received in the last three days by a new employee were 1, 2, and 8. Assume that samples of size 2 are randomly selected with replacement from this population of three values.

a. 1/9; 2/9; 1/9; 0/9; 1/9; 0/9; 1/9; 2/9; 1/9

b. 1/9; 1/9; 1/9; 1/9; 1/9; 1/9; 1/9; 1/9; 1/9

c. 1/8; 1/9; 1/8; 1/9; 1/8; 1/9; 1/8; 1/9; 1/8

d. 1/3; 1/3; 1/18; 1/6; 1/18; 1/9; 1/6; 1/18; 1/9
