Critical value(s) =
(Round to three 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

Are Presidents taller than their main opponents?
The table shows the heights of Presidents and their main opponents. Assume that the two samples are
randomly selected. At the 0.1 significance level, test the claim that the mean of the differences in the
heights of Presidents and their main opponents is greater than 0 cm (Presidents are taller than their main
opponents).
