Problem 5: Please answer parts a, b, and c!

A current area of research interest is the familial aggregation of cardiovascular risk factors in general, and lipid levels in particular. Suppose that it is known that the national average cholesterol level in children is 175 mg/dL. A group of men who have died from heart disease within the past year are identified, and the cholesterol levels of 57 of their offspring are measured. The average cholesterol level of the offspring is found to be 181.5 mg/dL with standard deviation 29.8 mg/dL.

At α = .06, can it be concluded that the average cholesterol level of children whose father died from heart disease is higher than the national average?

(a)	Find the value of the test statistic for the above hypothesis.

(b)	Find the critical value.

(c)	Find the p-value.

Problem #5: A current area of research interest is the familial aggregation of cardiovascular risk factors in general, and lipid
levels in particular. Suppose that it is known that the national average cholesterol level in children is 175 mg/dL.
A group of men who have died from heart disease within the past year are identified, and the cholesterol levels of
57 of their offspring are measured. The average cholesterol level of the offspring is found to be 181.5 mg/dL with
standard deviation 29.8 mg/dL.
At a = .06, can it be concluded that the average cholesterol level of children whose father died from heart disease
is higher than the national average?
(a) Find the value of the test statistic for the above hypothesis.
(b) Find the critical value.
(c) Find the p-value.
(d) What is the correct way to draw a conclusion regarding the above hypothesis test?
