And for the 95% confidence we need a significance level of
and
, the degrees of freedom are given by:

And the critical value would be

And replacing we got:


And the confidence interval for the difference is between:

The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours.
