according to the table and the information here,i need to decide if the two questions are correct or not.

so the information is this: Every student was examined in addition to the tasks also the Final Score.

Pearson correlation coefficient between number of task (X) and the Final Score (Y) has calculated and found to be equal to 0.75.

1)it is possible that Y=0.75X+96.25 ? here i think it not possible because the coefficient is not equal to 1 (except for 0.75) then this is not a linear relationship management is not possible to register the connection in the form of comparing linear as shown in the question. i would like if you can give me more reason why is not possible.

2)for each student that Submit assignment has more assignment that his Submit so the Final Score will be lower. here i need direction.

thanks.
