Question

Given a normal distribution with ? = 50 and ? = 5, 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) = 0.0228 (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) = 0.9759 (Type an integer or decimal rounded to four decimal places as needed.) c. What is the probability that X? is above 50.1? P(X? > 50.1) = 0.4207 (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? = (Type an integer or decimal rounded to two decimal places as needed.)

          Given a normal distribution with ? = 50 and ? = 5, 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) = 0.0228
(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) = 0.9759
(Type an integer or decimal rounded to four decimal places as needed.)

c. What is the probability that X? is above 50.1?
P(X? > 50.1) = 0.4207
(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? = 
(Type an integer or decimal rounded to two decimal places as needed.)
