The data below represent the number of days absent, x, and the final grade, y, for a sample of college students at a large univ. GO 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.) O A. For a final score of zero, the number of days absent is predicted to be days OB. For zero days absent, the final score is predicted to be O C. For every day absent the final grade falls by on average OD. For every unit change in the final grade, the number of days absent falls by days, on average OE. It is not appropriate to interpret the slope Interpret the y-intercept. Select the correct choice below and, if necessary, fill in the answer box to complete your choice (Round to three decimal places as needed)

W OA. No -15 missed dass periods is not possible OB. No –15 missed dass periods is outside the scope of the model OC. Yes -15 missed dass periods is possible and within the scope of the model OD. No -15 missed class periods is not possible and outside the scope of the model OE More information regarding the student is necessary to be able to make a decision
