19) It is known that average country song length is not normally distributed. Suppose a sample of 30 songs is taken from the population. The sample mean song length was 4.75 minutes with a sample standard deviation of 1.25 minutes. Construct a 99% confidence interval. Construct by finding the Margin of Error first. Then, after constructing the interval, verify using "TInterval" function on calculator. a) Find the T critical value. Tc = b) M.O.E = c) 99% Confidence Interval = d) Verify part c) above with stat function "TInterval". Give the parameters needed for "Tinterval" in order to obtain the Confidence Interval:
