Watch your cholesterol: A sample of 325 patients between the
ages of 38 and 82 were given a combination of drugs ezetimibe
and
simvastatin. They achieved a mean reduction in total cholesterol of
0.94 millimole per liter. Assume the population standard
deviation is 19.
Part 2 of 3
(b) Should this confidence interval be used to estimate the mean
reduction in total cholesterol for patients over the age of
90.?
The confidence interval (should/shouldnt) be used to estimate
the mean reduction in total cholesterol for patients over the age
of 90.
Homework Answers
The range for which we are making the confidence interval is for ages between 38 and 82 and hence, the confidence interval should not be used to estimate the mean reduction in total cholesterol for patients over the age of 90.
The answer is should not

5 of 8 patients were recruited to analyze the effects of various varia bles in explaining Total Cholesterol (mg/dL). Some of the variables included in this study are Age in years at screening, Weight (kg), Gender, Triglyceride (mg/d L), Direct HDL-Cholesterol (mg/dL), Fasting Glucose (mg/dL), and Systolic Blood Pressure (1st reading). A multiple regression was conducted to determine the extent to which Total Cholesterol (mg/dL) can be explained by these variables. Here is the output obta ined when a multiple...
