Playing violin causes students to get better grades.  

is a reasonable conclusion

Step-by-step explanation:

Given that the correlation coefficient for practicing violin and getting better grades in a group of people is 0.8.

If practicing violin time is taken as x and getting better grades is taken as y then we are given that x and y are positive strong correlated.  Strong because correlation coefficient is >0.5

Hence the given conclusion is reasonable.

Playing violin causes students to get better grades.  

D No; even though there is a strong positive correlation, playing violin doesn't cause students to get better grades
