I am taking an introductory level statistics class, and I need help interpreting the equation of the regression line, which is:
Predicted audience rating =-33 + 0.482 critics rating
According to the regression line, is it true that, on average, audiences tend to rate movies higher than critics do?
a)no, because the slope is less than one
b)no because the slope is less than one and the intercept is no 0
c)yes because the slope is positive
d) yes because the slope is positive and the intercept is positive.
I know for sure that the answer cannot be D. I plugged in values for critics rating to get the predicted audience rating to see the relationship, and I found that the critic's ratings were always lower than the audience's (I plugged in positive values). So my guess is that the answer is C.
Am I correct on this? If I could get help on this problem, I would greatly appreciate it. Thanks.
