The 5 summary statistics for the homework and final scores of 100 randomly selected students from a large Physics class of 2000 students are given in the table on the right. Avg SD Homework 78 8 r= 0.5 Final 65 15 a. Find the slope and y-intercept of the regression equation for predicting Finals from Homework. Round your final answers to 2 decimal places. Don't round in the intermediate steps. sure to enter y-intercept in the first blank and the slope in the second. Final = X Homework 提交答案| Tries 0/99 b. A 95% Confidence Interval for the population slope is closest to O(0.78 to 1.10) O(-0.94 to 2.81) O(0.31 to 0.63) O(0.62 to 1.26) 提交答案 Tries 0/99 c. To test the null hypothesis Ho: slopepop = 0 against the alternative HA: slopepop + 0 we'd compute a z statistic. Select the closest Z statistic. O0.05 O0.577 O5.77 O57.7
