Round off to 4 decimal places.This is 1 question that has 3 sub-parts, please answer all from a-c It is argued that more time spent studying will result in improved course marks among ECO242 students. To te:whether this is the case you collect data from 30 students on their final marks (Y) and number of hours studieper week during the semester (X). You make the following calculations:ΙΣΧΥ | 37832 |ΣΧ14964ΣΧΣΥNext, you run the following regression:marks =B₁ + B₂studyhours6321650where 'marks' is the final mark for the course in percentage points, and 'studyhours' is the number of hours.studied per week during the course semester. Answer the remaining questions based on your results.a)b)If the total sum of squares is 14648, the residual sum of squares is 8928. What is the value of2₁How would you interpret your result above (the value determined for 7.²?A. The variation in weekly study hours explains close to 40% of the variation in marks.OB. The variation in weekly study hours explains almost none of the variation in finalmarks for the course.O C. The variation in weekly study hours does not explain any of the variation in finalmarks.c)O D. Variation in weekly study hours explains a significant proportion of the variation instudy time.Given your answers above, you conclude that...OA. The null is not rejected since the test statistic is smaller than the critical value and lieswithin the acceptance region of the sampling distribution.OB. The null is not rejected since the test statistic is larger than the critical value and lieswithin the rejection region of the sampling distribution. Thus we conclude that more hoursper week spent studying has, on average, a positive effect on the final mark for the course.OC. The null is rejected since the test statistic is larger than the critical value and lieswithin the rejection region of the sampling distribution. Thus we conclude that more hoursper week spent studying has, on average, a positive effect on the final mark for the course.OD. The null is accepted since the test statistic is larger than the critical value and lieswithin the acceptance region of the sampling distribution. Thus we conclude that morehours per week spent studying has, on average, a positive effect on the final mark for thecourse.O E. We reject the null hypothesis because the estimated coefficient is a positive value.Thus we conclude that more hours per week spent studying has, on average, a positiveeffect on the final mark for the course.

a. The coefficient of determination, denoted as r2, represents the proportion of the total sum of…
