Question

Elevated cholesterol levels pose a risk of heart disease. For 20 – 74-year-olds males in the United States, cholesterol level is normally distributed. Cholesterol levels above 220 are considered to of moderate risk. Health officials feel cholesterol levels of male college students may be of concern because of diet or lack of exercise. To test this premise, the cholesterol levels of 13 male students in three different classes at Montgomery College were measured and found to have a mean of 229 mg/100ml and standard deviation of 46 mg/100ml.

The current sample size is 39. Would decreasing the sample size indicate less, more, or the same concern? Explain.
