he table shows the pain levels of patients before and after hypnotism. Pain level is measured on a cm scale.

Does Hypnotism Relieve Pain?

The table shows the pain levels of patients before and after hypnotism. Pain level is measured on a cm scale. Assume that the two samples are randomly selected. At the 0.05 significance level, test the claim that the mean difference has increased after hypnotism.
(Be sure to subtract in the same direction).

Based on the hypotheses, find the following:
Test Statistic =
(Round to three decimal places.)
Critical value(s) =
(Round to three decimal places.)
p-value =
(Round to four decimal places.)
Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions. The
arrows can only be dragged to t-scores that are accurate to 1 place after the decimal point (these values
correspond to the tick marks on the horizontal axis). Select from the drop down menu to shade to the left,
to the right, between or left and right of the t-score(s).
Shade: Left of a value
Click and drag the arrows to adjust the values.
