  1. Z-Test and T-test

    Question 1 of 3

    • Load heart_diseases_cleaned dataset and test: - Is average age of heart disease patients greater than 50 years? - Is average cholesterol level of heart disease patients different from 200 mg/dL? - Is average sysBP of heart disease patients lesser than 120 mmHg? - Is average sysBP different between stroke vs non-stroke patients? - Do people with diabetes have higher glucose levels than non-diabetics?

  2. Chi-Square Test

    Question 2 of 3

    • Load heart_diseases_cleaned dataset and test: - Association between heart stroke and diabetes. - Association between heart stroke and gender. - Association between heart stroke and smoking status. - Association between diabetes and age group (young, middle-aged, old). - Association between smoking status and age group (young, middle-aged, old).

  3. ANOVA

    Question 3 of 3

    • Load heart_diseases_cleaned dataset and test: - Is average sysBP different across age groups (young, middle-aged, old)? - Is average glucose different across BMI (underweight, normal, overweight, obese)? - Is average cigsPerDay different across exercise frequencies? - Is average diaBP different across academic levels?
