Can anyone please help me answer question B from (I, ii, iii to A, B, C)?

I am suffering A LOT..

(b) A random sample of twelve students were chosen, and their midterm test score (y), as- signment score (21), and missed classes (x2) were recorded as follows: Midterm Assignment Classes Score, y Score, 1 Missed, x2 85 65 74 50 76 55 90 65 85 55 87 70 94 65 98 70 81 55 91 70 76 50 74 55 (i) What is the fitted multiple linear regression equation of the form y = bo + b121 + 62x2? [3 marks] (ii) From part 6(b)(i) above, estimate the midterm test score grade for a student who has an assign- ment score of 60 and missed 4 classes. [1 mark] (iii) Assume that the data on (y, 21, 22) above in 6(b) is inputted into SPSS, with the following results: ANOVA Coefficients Standard error Source SS df MS F Intercept 27.547 12.498 Regression C g Assignment Score 0.922 0.186 Residual 5 d 20.406 Missed Classes 0.284 0.754 Total 728.250 e A. At 5% level of significance, test whether the individual variables, assignment score (x1), and missed classes (2) are significant explanatory variables for the midterm test score. [3 marks] B. Find the constants a, b, c, d, e, f and g in the ANOVA table. [2 marks] C. Test the overall significance of the multiple linear regression model/equation in (i) at 1% level of significance. [3 marks]
