#1.       You are to construct a 99% confidence interval of a normally distributed population; the population standard deviation is known to be 25. A random sample of size 28 is taken; (i) the sample mean is found to 76 and (ii) the sample standard deviation was found to be 30. Construct the Confidence interval. Clearly name the standard distribution you used (z, or t or F etc.) and show work. (10 points)
