Given a normal distribution with

=110

and

=10,

and given you select a sample of

n=4,

complete parts(a) through(d).

a. What is the probability that overbarX

is less than 100?

b.What is the probability that overbarX

is between 100

and 102.5?

c. What is the probability that

overbarX

is above

112?

There is a

55%

chance that overbarX

is above whatvalue?
