The data below represent the number of days absent, x, and the final grade, y. for a sample of college students at a large university Complete parts (a) through (e) below 4 5 No. of absences, x Final grade, y 0 1 2 3 6 7 8 90 89.1 86 1 831 80.5 77.5 73.0 63.7 67.8 64.8 61.9 (a) Find the least-squares regression line treating the number of absences, x, as the explanatory variable and the final grade, y, as the response variable (Round to three decimal places as needed) (b) Interpret the slope and y-intercept, if appropriate Interpret the slope: Select the correct choice below and, if necessary, fill in the answer box to complete your choice (Round to three decimal places as needed) OA. For every day absent, the final grade falls by on average OB. For zero days absent, the final score is predicted to be days OC. For a final score of zero, the number of days absent is predicted to be OD. For every unit change in the final grade, the number of days absent falls by OE. It is not appropriate to interpret the slope. Statcrunch Tune here to search CETTE O days, on average Time Re 77°F Mostly a
