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
