Problem 8: The Framingham Heart Study was a longitudinal cohortstudy of 5000+ men and women. One outcome of interest was fastingglucose levels. Glucose levels were categorized into threedifferent categories:
Glucose Levels
-Diabetes (glucose >126),
-Impaired Fasting Glucose (glucose100-125),
-Normal Glucose
Several possible risk factors were also recorded:
Risk Factors
-Sex
-Age
-BMI (normal weight, overweight,obese)
-Genetics
To determine if each possible risk factor is related to glucoselevels,researchers need to use an appropriate hypothesis test.
Test Choices
1. ANOVA
2. Chi-Square GOF
3. Chi-Square test for independence
4. Test for equality of means
5. Test for equality of proportions
6. Other
a. What test would be used to assess whether the differentsexes(male and female) have the same proportions of the differentglucose levels?
b. What test would be used to assess whether the differentglucose levels have the same mean age?
c. What test would be used to assess whether the differentcategories of BMI have the same proportions of the differentglucose levels?
