Q3

Q3 Conduct the Tukey- Kramer test to determine which age groups consume calories significantly different from each other.

Q4

Q4 Now you want to explore if a regression model could be developed to predict calories in take based on the relevant variables in the data.
Q4A Run a correlation matrix involving all numerical variables in the data.
Q4B Run simple regression with most promising variable to predict calories.
Make sure that you click on residual plots and normality curve.
Q4C Test all four assumptions of regression analysis.

Q5

Q5 Going back to the correlation matrix, add more independent variables as appropriate to determine the best regression model.
Explain why the model selected is the best.

Q6

Q6 One analyst is curious if one can predict using this data if someone is a smoker.
To this end, she wants you to develop a logistic regression model using only the numerical variables.
A Develop such a model using age, Fat and alcohol.
B Remove the insignificant variables ad rerun the logistic regression.
C Assuming some reasonable values of the significant variables, calculate the probability of
