(a) Suppose a random sample of size n= 25 from a normal population with unknown variance has sample mean = 50 and sample variance s2 = 64. Construct a 100(1-a)% Confidence Interval (C.I.) for the population mean u with a = 0.10, a = 0.05 and a = 0.01. )Find the lengths of the intervals constructed above. What is the relationship between the confidence level (1-a) and the length of C.I.?
