All help is much appreciated please and thank you

Part A:

I think there is a correlation because the more hours a student spends browsing the lower his score is. If you calculate the correlation coefficient you would get -0.9963777 meaning there is a strong negative correlation.

Part B:

The function that best represents the data is y=-2.2545x+95

Part C:

The slope is -2.2545 meaning for every unit of x y decreases by -2.2545. The y intercept is 95 meaning when x equal 0 y equals 95.

HOPE THIS HELPS :)
