For a sample of

nequals=6464,

the probability of a sample mean being less than

21.521.5

if

mu equals 22μ=22

and

sigmaσequals=1.171.17

is

Answer #1

The population mean and standard deviation are given below. Find
the indicated probability and determine whether a sample mean in
the given range below would be considered unusual. If convenient,
use technology to find the probability. For a sample of n=40, find
the probability of a sample mean being less than 12751 or greater
than 12754, when mean = 12751 and standard deviation = 1.6.
