Homework 3 November 7 1. Using question 12 (delaying major purchases) as the response variable (Y) compute a regression model with the following questions 9, 25 (gender: males as 0 and females coded as 1) as your predictor variables. You will have to use the data set Economic Gun Legislation Survey Regression Exercise posted for Session 5 on the webpage . Please do the following in exactly this order : a. Excel Output b. Model : write down model like in form y = b 0 + b 1 X 1 +b 2 X 2 +…+ b k X k using Excel output to put in actual coefficients. Y^= 4.58 + 0.03 (Q9) – 0.02 (Q25) c. Interpret the slope coefficient: Report and interpret the slope coefficient for variable q25 (gender). As we increase Q25 by 1 unit, we increase y (Q12) by .03 units d. Predictiveness of variable q25 (gender): Determine whether q25 is predictive of Y using both the p-value and confidence interval approaches. Use alpha = .05 for p-value and 95% for confidence interval. X is not predictive of y since the p-value of x (Q25) is 0.91 which is > than , then conclude x is not predictive of y.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
