(use twо decimаls) The fоllоwing R output presents results on predicting GPA in high school students using the dаys of аbsence as the predictor variable. Use this information to answer the following questions: midterm_Q33_1.png midterm_Q33_2.png (a) How much (%) of the variability in GPA is predicted by days of absence? [BLANK-1] (b) What is the raw score regression equation for GPA using absence? [BLANK-2] (c) What would be the predicted GPA score for a student who doesn't have any absence? [BLANK-3] (d) What would be the predicted GPA score for a student who is absent for 10 days? [BLANK-4] (e) What is the standard error of prediction for GPA using days of absence? [BLANK-5] (f) What is the 95% confidence interval of the predicted GPA of a student who is absent for 10 days? (z_95%CI=1.96) [BLANK-6] (g) What is the standardized regression equation for predicting GPA using days of absence using z scores of y and x? [BLANK-7]
