16) At one college, the GPA's are Normally distributed with a population standard deviation of 0.6. From a random sample, the mean GPA of 20 students was 2.8. Construct a 99% confidence interval. Construct by finding the Margin of Error first. Then, after constructing the interval, verify using "ZInterval" function on calculator. a) Find the Z-critical value. Zc = b) M.O.E= c) 99% Confidence Interval = d) Verify part c) above with stat function "ZInterval". Give the parameters needed for "ZInterval" in order to obtain the Confidence Interval:
