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 studie per week during the semester (X). You make the following calculations: |EXY|37832| ΣΧ |14964 ΣΧ 632 ΣΥ 1650 Next, you run the following regression: marks =B₁ + B₂studyhours where '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. Round off to 4 demimal places. a) The value for the intercept parameter is? b) If the standard error for the slope parameter estimate is 0.439617, construct a 95% confidence interval for the parameter. Pr SB₂ ≤ )=95% c) If the standard error for the slope parameter estimate is 0.439617, construct a 95% confidence interval for the parameter. Pr
