Please help me with this problem. Can you tell me how to calculate the P-value using these numbers on a TI-84 Calculator?

The data table represents the measure of a variable before and after a treatment. Does the sample evidence suggest that the treatment is effective in decreasing the value of the responsevariable? Use the

=0.10level of significance. Complete parts(a)through(d).

Individual

1 2 3 4 5

Before,xi 38 32 55 49 37

After,yi 38 33 50 49 33

(a)What type of test should beused? Choose the correct answer below.

A.A hypothesis test regarding the difference between two population proportions from independent samples. (I selected this answer)

B.A hypothesis test regarding the difference of two means usingWelch's approximate t.

C.A hypothesis test regarding the difference of two means using amatched-pairs design.

D.A hypothesis test regarding two population standard deviations.

(b)Determine the null and alternative hypotheses. Letd=xy.

Choose the correct answer below.

A.H0:d=0;H1:d<0 (I selected this answer)

B.H0:d=0;H1:d0

C.H0:d=0;H1:d>0

D.H0:d0;H1:d>0

(c)Use technology to calculate the

P-value.

(Round to three decimal places asneeded.)

(d)Draw a conclusion based on the hypothesis test. Choose the correct answer below.

A.Thereissufficient evidence to reject the null hypothesis because the P-value<.

B.Thereisnotsufficient evidence to reject the null hypothesis because the P-value>.

C.Thereisnotsufficient evidence to reject the null hypothesis because the P-value<.

D.Thereissufficient evidence to reject the null hypothesis because the P-value>.
