If we have a population consists of 5 people and their wights in kilograms are:
76, 58, 64, 82, 60
Calculate both mean and variance for the wights of this population,
If we select randomly a sample of 2 individuals with replacement, find the mean and and the variance for
possible samples,
Repeat part b if the sampling without replacement,
Calculate the mean and the variance for samples population for both part b and c,
Compare the mean and variance of the samples population with those of original population.
Expert Solution
Step 1
Hint:
Sample mean
Sample variance
Number of possible samples if samples are selected with replacement = Nn
Number of possible samples if samples are selected without replacement = NCn
