Question

random sample of nine from the men of a large city gave a mean height of 68

inches, and the unbiased estimate of the population variance from sample, variance was 4.5

inches. Are these data consistent with the assumption of a mean height of 68.5 inches for the

men of the city?​

Answer 1

Answer

If we draw a sample of size ‘n’ from the given finite population of size N, the possible samples are NCn = k (say)

If we draw a sample of size ‘n’ from the given finite population of size N, the possible samples are NCn = k (say)For each of these ‘K’ samples we can compute some statistic t= t(x1,x2….xn), in particular the mean and the the variance are given below
