Given a normal distribution with μ equals 50 and σ equals 3, complete parts a through d

a) What is the probability that X>45?

?P(X>45) =

?(Round to four decimal places as? needed.)

b) What is the probability that X<47?

?P(X<47) =

?(Round to four decimal places as? needed.)

c) For this? distribution, 5?% of the values are less than what? X-value?

X=

?(Round to the nearest integer as? needed.)

d) Between what two? X-values (symmetrically distributed around the? mean) are 60?% of the? values?

For this? distribution, 60?% of the values are between X= ? and X= ?

?(Round to the nearest integer as? needed.)
