Supermarket Store A wants to determine whether prices at their competitor are lower than at their store. Researchers randomly selected ten items and compared the prices at each store.

Item	1	2	3	4	5	6	7	8	9	10
Store A	2.63	1.19	3.99	3.79	2.99	1.49	4.89	4.25	2.19	2.99
Other Store	2.48	1.00	3.09	3.29	2.99	1.89	4.39	4.00	2.99	2.79

1. Compute a 95% confidence interval for the true mean difference in prices between the two stores, assuming conditions have been met. Be sure to show all of your work and interpret your interval.
2. Based upon your confidence interval in question 1, is there evidence that the other store's prices are different? Explain.
