Major league baseball salaries averaged$3.26 million with a standard deviation of$1.2 million in a certain year in the past. Suppose a sample of 100 major league players was taken. Find the approximate probability that the mean salary of the 100 players was less than$2.5 million, rounding to four decimal places. Suppose a95% confidence interval for turns out to be(1,000, 2,100). To make more useful inferences from thedata, it is desired to reduce the width of the confidence interval. Which of the following will result in a reduced intervalwidth?
A. 0.2633
B. 0.0000
C. 0.9849
D. 0.0151
