Question: A population of values has a normal distribution with = 216.1 = 216.1 and = 56.9 = 56.9 . You intend to draw a random

A population of values has a normal distribution with

=

216.1

=

216.1

and

=

56.9

=

56.9

. You intend to draw a random sample of sizen

=

126

n

=

126

.

a.) Find the probability that asinglerandomly selected value is less than 208.

P(X< 208) =Incorrect

b.) Find the probability that a sample of sizen

=

126

n

=

126

is randomly selected with a mean less than 208.

P(M< 208) =Incorrect

(Here M is the mean of the sample)
