Reference no: EM132847036

We take a simple random sample without replacement of a population of size N = 1000 yields the following 20 values:

52 64 71 54 58
61 54 56 81 43
55 65 53 47 51
54 71 66 68 70

i) Calculate an unbiased estimate of the population mean

ii) Calculate unbiased estimates of the population variance and ?Var(X¯n?)

iii) Use the unbiased estimate of the variance of ?X¯n?? from part ii to give an approximate 95% confidence interval for the population mean.
