(iii) Hours Spent Studying (b) Develop an estimated regression equation showing how total points earned is related to hours spent studying. What is the estimated regression model? Let x represent the hours spent studying. If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300 ) y^= studying is zero. The interpretation of 0 is not reasonable but the interpretation of 1 is reasonable. time spent studying. The interpretation of 0 is not reasonable but the interpretation of 1 is reasonable. time spent studying. The interpretation of 0 is reasonable but the interpretation of 1 is not reasonable. zero. Both interpretations are reasonable. (d) How much of the variation in the sample values of total point earned does the model you estimated in part (b) explain? If required, round your answer to two decimal places. (e) Mark Sweeney spent 90 hours studying. Use the regression model you estimated in part (b) to predict the total points Mark earned. If required, round your answer to the nearest whole number. Do not round intermediate calculations.
