Given a normal distribution with mu = 50 and sigma = 4 , and given you select a sample of n = 100 complete parts (a) - (d). Round to four decimal places as needed on (a) - (d) a. What is the probability that overline x is less than 49? b. What is the probability that overline x is between 49 and 49.5? c. What is the probability that overline x is above 50.4? d. there is a 40% chance that overline x is above what value?
