Chapter 7: Essentials of Biostatistics for Public Health

You will be using your Framingham dataset to answer the following question. You will be performing hypothesis testing. For each question, please write out the null hypothesis, alternate hypothesis, and which test statistic you will be using (based on variable type). Then report the results from performing the analysis using SPSS. Please report the test statistic, significance level, and whether you will accept or reject the null hypothesis and why. Then, if there are statistically significant differences, interpret your findings.

 1. Are there differences between smokers and nonsmokers in systolic blood pressure?

2.  Are there differences between smokers and nonsmokers in total serum cholesterol?

3.       Are there differences between smokers and nonsmokers in rates of prevalent coronary heart disease?

4.       Are there differences between smokers and nonsmokers in rates of prevalent hypertension?

5.       Are there differences for people in different BMI categories in systolic blood pressure?

6.       Are there differences for people in different BMI categories in total serum cholesterol?

7.       Are there differences for people in different BMI categories in rates of prevalent coronary heart disease?

8.       Are there differences for people in different BMI categories in rates of prevalent hypertension?

    An investigator theorizes that people who exercise regularly will have mean systolic blood pressure levels that are significantly different from those of people who do not participate in a regular exercise program. To test this idea, the investigator randomly assigns 21 subjects to an exercise program for 10 weeks and 21 subjects to a non-exercise comparison group. After ten weeks, the mean systolic blood pressure of subjects in the exercise group is 132 and the standard deviation is 10. After...
