An article in the Archives of Internal Medicine reported that in a sample of 244 men, 73 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 232 women, 44 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is greater than the proportion of women? Let M denote the proportion of men with elevated cholesterol levels and let W denote the proportion of women with elevated cholesterol levels. Use the level of significance and the critical value method. (a) Write the hypotheses for the test.(b) Calculate the difference in sample proportions between groups.(c) Using 2PropZTest, calculate a P-value.(d) Fill in the blanks to explain what the P-value means: If there is between the proportions of high cholesterol, then there is a ___ % chance that there is a or percentage point difference between the high cholesterol rates.(e) What is your decision about the null hypothesis? Why?
