Given a normal distribution with u = 50 and o =8, and given you select sample of n= 100, complete parts (a) through (d). a. What is the probability that X is less than 49? P(X< 49) = (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that X is between 49 and 51,5? P(49 50.6) =O (Type an integer or decimal rounded to four decimal places as needed.) d. There is a 40% chance that X is above what value?

Given a normal distribution with u = 50 and a = 8, and given you select a sample of n= 100, complete parts (a) through (d). a. What is the probability that X is less than 49? P(X<49) = (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that X is between 49 and 51.5? P(49 <x<51.5) =O (Type an integer or decimal rounded to four decimal places as needed.) c. What is the probability that X is above 50.6? P(X> 50.6) =D (Type an integer or decimal rounded to four decimal places as needed.) d. There is a 40% chance that X is above what value? x-D (Type an integer or decimal rounded to two decimal places as needed.) Enter your answer in each of the answer boxes.
