Hi, I need help solving this problem out:
Let A, B, C, D, and E are 6 units of a population. The measurements associated with A, B, C. D, E units are 76, 77, 78, 81, and 82, respectively.
-Find the population mean and its standard deviation (Answered)
-List all possible samples of size 3 from those 5 units
-From each sample, compute the mean, standard deviation, and 95% confidence interval. Use t-distribution to estimate the t?/2 because we have a small size.
-How many intervals contain population mean? Can you verify your result with empirical rule? Do they agree?
I found the mean and standard dev they are 78.8 and 2.58844
