In their advertisements, the manufacturers of a certain brand of cereal would like to claim that eating their oatmeal for breakfast daily will produce a mean decrease in cholesterol of more than 10 mg/dl in one month for people with cholesterol levels over 200 mg/dl. In order to determine if this is a valid claim, they hire an independent testing agency, which then randomly selects 25 people with a cholesterol level over 200 for inclusion in a study. The 25 people in the study eat this cereal for breakfast daily for a month. Which of the following is the alternative hypothesis of interest in this study? A. Ha: μ < 10 B. Ha: μ > 10 C. Ha: μ 10 D. Ha: > 10
