3. Question 3 Use the SAS programXcode \"PRESSURE" under the heading \"Question 3" in order to answer the question 3. prbefore & prAfter These are tests conducted before and after a stimulus is applied to 12 men to determine its effects on systolic blood pressure. 3.]. Perform a paired sample T-Tesl for the difference between SBP {Systolic Blood Pressure) taken before and after the stimulus of 12 individuals. (Note: Add a title Paired Sample T Test) 3.2. One must provide a brief explanation and state the hypothesis concerning the paired sample TTest. (Note: state all the steps and conclusions of the hypothesis.)

Question 4 Copy the SAS program/code "FATCOMP" under "Question 4" in order to answer question 4 The dataset "FATCOMP" contains hypothetical data for a case-control study of high fat diet and the risk of coronary heart disease. Variables Description Exposure A binary variable which includes ( 1 = High Cholesterol Diet) & (0 = Low Cholesterol Diet) Response 1 = Yes and 0 = No, Response indicates whether the individual is susceptible to heart disease. Count The data is recorded as cell counts which is the frequencies of exposure and response. 4.1. Create code that will perform a Chi-Square independence test between the variables EXPOSURE and RESPONSE using "PROC FREQ". The significance level for this Chi-Square test is 0.01. Assign the variable COUNT as the weight. (Note: RESPONSE = Heart Disease). 4.2. Add a title "Chi-Square test if independence" to the output. 4.3. Use the output generated above to conclude whether there is a relationship between individual's cholesterol diet and heart disease. (Note: state all the steps and conclusions of the hypothesis.)
