For the above two questions: A particular Starbucks wants to know on average how many people go to this Starbucks each day. The standard deviation for the number of people at this Starbucks is 20 people per day. In a sample of 20 days on average 94 people per day showed up. Find an 80% Z-confidence interval for the true average number of people that go to this Starbucks each day. Is it true that 100 people too high for the true average number of people that go to this Starbucks?
