![According to a recent poll, 28% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to
the regions healthcare system" and are a major concern to health insurance providers. According to recent studies, cholesterol levels in healthy adults from the
area average about 207 mg/dL, with a standard deviation of about 20 mg/dL, and are roughly Normally distributed. Assume that the standard deviation of the
recent studies is accurate enough to be used as the population standard deviation. If the cholesterol levels of a sample of 44 healthy adults from the region is
taken, answer parts a through d.
a) What shape will the sampling distribution of the mean have?
A. The sampling distribution of the mean is skewed right.
B. The sampling distribution of the mean is normal.
C. The sampling distribution of the mean is skewed left.
