A population has mean 128 and standard
deviation 22
A. Find the mean and standard deviation of
for samples of size 36.
B. Find the probability that the mean of a
sample of size 36 will be within 10 units of
the population mean, that is, between 118
and 138. Chint, since the samples are over
30, CLT states that it is normal and we can
use normalcdf)
a. mean = 128. sd-36
b. .0005
a. mean = 128, sd - 3.67
b..821
a. mean = 128, sd - 3.67
b..9936
a. mean 128, sd 38
b. .9999
