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

Recognize 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 at random 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
