Much discussion has appeared in the medical literature in recent years on the role of diet in the development of heart disease. The serum-cholesterol levels of a random sample of n = 24 people who eat a primarily macrobiotic diet were measured. Their average cholesterol level was found to be ¯x = 195 milligrams per deciliter with standard deviation of s = 35 milligrams per deciliter. The cholesterol levels in the general population in this age group have mean of...

A large study involving over 20,000 individuals shows that the mean percentage intake of kilocalories from fat was 39% with a range from 6% to 72%. A small sample study was conducted at a university hospital to determine if the mean intake of patients at that hospital was different from 39%. A sample of 15 patients had a mean intake of 40.8% with a standard deviation equal to 6.5%. Assume that the sample is from a normally distributed population. Use...
