f Y ^ = - 0.5 + 11.6X.
a) Interpret the value of the slope.
b) Estimate the mean of the response variable when x = 0.48
a.) Interpretation of the slope:
The interpretation of the slope is:
If we increase 1 unit in x, there will be 11.6 unit increse in y.
b.) mean of response varibale when x=.48:

Hence the ans is 5.068

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 Week 9 on the webpage. Please do the following in exactly this order: a. Excel Output b. Model: write down model like in form y- b, b,X, -b.X. +...
a. We have seen in class that we can obtain the estimate of the slope vector B(o) by transforming the data into deviations from the corresponding sample means (for both the response variable Y and the predictors X(o)). And we then regress the transformed Y on the transformed predictors to obtain esti- mates of the slopes. Do we get the same result if we only transform Y? What if we only transform X(o)?
