Variable	Count	Mean	StdDev
Local	10	901.700	372.804
Online	10	844.300	308.623
Diff	10	57.4000	180.760

Compute the test statistic.

The test statistic is?

​(Round to two decimal places as​ needed.)

Find the​ P-value.

The​ P-value is

There is insufficient/There is

evidence that drivers would save money by switching because the​ P-value of the appropriate hypothesis test is large/small
