Answer the questions using the result of minitab.
IQ's are normally distributed with u =100 and o = 12. Take random sample of size 100
and repeat the process to calculate the mean of the sample. 1)How does the mean of the
sampling distribution µz compare to the mean of the original population µ. 2)How does
the standard deviation of the sampling distribution o, compare to the standard deviation
of the original population o. 3)How does the shape of the sampling distribution compare
to the of the original population? 4) calculate p (X>104)
Generate 100 random samples of size n=40 from Normal (u=80, sd3D5), calculate
confidence intervals for mean and check how many failed to correctly estimate u?
Example10.MTW. Variable exam2, calculate confidence interval and decide if the mean
less than 80
