Q1 (please note that this is made-up!) Culver's claims that their mint chocolate chip custard has 18 chocolate chips per scoop on average. A customer thinks this is incorrect because his random sample of 15 scoops produced 16.8 chocolate chips with standard deviation of 2.6 chips. Test the customer's claim with significance level of .01. Q2 It is known that, nationally, doctors working for HMOs average 13.5 years of experience in their specialties, with a standard deviation of 7.6 years.

A random sample of 150 doctors from HMOs shows a mean of only 11.9 years of experience. Test the executive director's claim that the HMO's doctors average less experience than the national average, with a signicance level of .01
