1. Do these results allow us to conclude at the 1% significance level that the model is useful in predicting the fourth-year medical course final grade?
2. Do these results allow us to conclude at the 1% significance level that on average medical majors outperform those whose majors are not medical or biology?
3. Do these results allow us to conclude at the 1% significance level that on average biology majors outperform those whose majors are not medical or biology?
4. Do these results allow us to conclude at the 1% significance level that grade point average in first three years is linearly related to the fourth-year medical final grade?

I have attached related information and question below.

Could you please explain them in detail?

Thank you very much

Senior Medical Students A professor of Anatomy wanted to develop a multiple regression model to predict the students' grades in her fourth-year medical course. She decides that the two most important factors are the student's grade point average in the rst three years and the student's major. She proposes the model y = ,8; + [31x1 + zxg + m + a, where y = Fourth-year medical course nal score (out of 100), x1 = G.P.A. in rst three years (range from 0 to 12), x2 = 1 if student's major is medicine and 0 if not, and x3 = 1 if student's major is biology and 0 if not. The computer output is shown below. THE REGRESSION EQUATION [S y = 9.14 + 6.73x1+10.42xg + 5.16x3 Coe s = 15.0 RSq = 44.2% ANALYSIS OF VARIANCE a!
