Probability
Given a normal distribution with u = 103 and a = 10, and given you select a sample of n = 4, complete parts (a) through (d). a. What is the probability that X is less than 93? P(X< 93) = 0.0228 (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that X is between 93 and 93.5? P(93 103.6) = 0.4522 (Type an integer or decimal rounded to four decimal places as needed.) d. There is a 68% chance that X is above what value? (Type an integer or decimal rounded to two decimal places as needed.)
