Question
A food manufacturer claims that eating its new cereal as part of a daily diet lowers total blood cholesterol levels. The
table shows the total blood cholesterol levels (in milligrams per deciliter of blood) of seven patients before eating the
cereal and after one year of eating the cereal as part of their diets. Use technology to test the mean difference.
Assume the samples are random and dependent, and the population is normally distributed. At x = 0.05, can you
conclude that the new cereal lowers total blood cholesterol levels?
