Question 1. Based on your hypothesis, you believe a respondent’s… 1. Based on your hypothesis, you believe a respondent’s self-reported poor health is related to their demographics (_AGE_G, SEX1, _RACE_G1, _EDUCAG) and other select factors (_BMI5, AVEDRNK2, and SEATBELT). Run a multiple linear regression using PROC REG including only the demographic variables (use dummy variables not original categorical variables).  a). How many observations were used compared to the original sample? (2 pts)b.) Does this model meet our assumptions for linear regression? Briefly describe your synopsis. (2 pts) c.) What is the adjusted R2? Interpret this value. (2 pts) d.) Is the omnibus null significant at  ?=0.05? What is the p-value? (2 pts) e.) What is the predicted value of self-reported number of days experiencing poor physical or mental health for Males (Set all other variables to 0)? Is this value significant? Report p-value. (2 pts) f.) Interpret the beta coefficient for respondents who did not graduate high school.

Now, run a multiple linear regression on the same variables but now include your other factors of interest.  a). What do _BMI5, AVEDRNK2, and SEATBELT represent? Use codebook. (2 pts) b). How many observations are used in this analysis? If different from the previous model, why do you believe that is? (2 pts) c). How does the adjusted R2 change? Interpret the change in R2 from Q1. Why is the Adjusted R2 different than the R2? (2 pts) d). Report the predicted value of self-reported number of days experiencing poor health for Males. How does it change? (2 pts) e). Interpret the beta coefficient for AVEDRNK2. (2 pts) f). Were there any variables which were significant in the first model that were no longer significant in the second? If any, which ones and why may this have happened?
