a) How does the mean of any sampling mean distribution compare to the population mean?
The expected value of sampling mean is equal to the population mean
b) Explain what happens to the spread of the sample mean distribution as the sample size increases based on the results observed in this lab.
The spread or the standard deviation of the sample mean decreases as the sample size increase

A variable of a population has a mean and a standard
deviation .
a. The sampling distribution of the sample mean for samples of
size 49 is approximately normally distributed with mean and
standard deviation of
Mean = 100 and standard deviation = 3
Mean = 14.28 and standard deviation = 3
Mean = 14,28 and standard deviation = 0.428
Mean = 99 and standard deviation = 9
