The value for the slope parameter is?
Transcribed Image Text: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:
37832
14964
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.
