Question

Ten subjects with borderline-high cholesterol levels were randomly recruited for a study that involved taking a nutrition education class. Cholesterol readings were taken before the class and 3 months after the class.
Let d = preclass cholesterol - postclass cholesterol. Excel was used to find the 95% confidence interval for the mean amount of reduction in cholesterol readings after taking the nutrition education class. Verify the results shown on the output by calculating the values yourself. Assume normality.
