Editing 3) Dominos Pizza for years made a claim that they would deliver your pizza within 30 minutes ("30 minutes or less") of your order being placed (provided you live within a certain radius of their restaurant). A group of college students make the ultimate sacrifice and order Dominos from the same location for 20 straight days for the good of statistics. They find a mean of 23.7 minutes and a standard deviation of 2.15. A) In constructing a 95% confidence interval for mean wait time for Dominos Pizza delivery using the data collected by the students, would your critical value be a z* or a t*? Explain your answer. B) Staying consistent with your answer to part A, construct a 95% confidence interval for mean wait time of Dominos Pizza delivery. C) Do you think this confidence interval is accurate for Dominos Pizza in general? Why or why not?
