Question

Insurance adjusters are concerned about the high estimates
they are receiving from Jocko’s Garage. To see if the estimates are unreasonably high, each of 10 damaged cars was taken to Jocko’s and to another garage and the estimates (in dollars) were recorded. Here are the results:

Car	1	2	3	4	5	6	7	8	9	10
Jocko's	1410	1550	1250	1300	900	1520	1750	3600	2250	2840
Other	1250	1300	1250	1200	950	1575	1600	3380	2125	2600

(b) Test the null hypothesis that there is no difference between the estimates of the two garages. Be sure to specify the null and alternative hypotheses, the test statistic with degrees of freedom, and the P-value. What do you conclude using the 0.05 significance level?
