There were 855 major league baseball players in 2012 and their mean salary was = 3.44 million dollars with standard deviation = 4.70 million dollars. If we take random samples of size n = 30 players and calculate the mean salary, in millions of dollars, of each sample, describe the shape, center, and standard error of the distribution of sample means
: Using the t-Distribution
(a) Find endpoints of a t-distribution with 5% beyond them in each tail if the sample has size n = 18.
(b) Find the area in a t-distribution to the right of 2.30 if the sample has size n = 15.
(c) Find the area in a t-distribution to the left of 1.22 if the sample has size n = 50.
