Answer #1

Let us denote the difference

d = Before - After

Conclusion :

There is not sufficient evidence to support the claim that the tutoring has an effect on the math scores.

To calculate critical value in TI 83, command : invT(0.995, 4)

To calculate P-value in TI 83, command : 2*tcdf(E-99, -2.134, 4)
