Actual question is attached in the image.



The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same sample of days. After choosing a random sample of  days, she records the sales (in dollars) for each store on these days, as shown in Table 1.

Day Store 1 Store 2 Difference
(Store 1 - Store 2) 
1 754 806 -52 2 448 647 -199 3 284 169 115 4 645 440 205 5 759 628 131 6 440 340 100 7 214 239 -25 8 752 700 52
Table 1

Based on these data, can the owner conclude, at the  level of significance, that the mean daily sales of the two stores differ? Answer this question by performing a hypothesis test regarding  (which is  with a letter "d" subscript), the population mean daily sales difference between the two stores. Assume that this population of differences (Store 1 minus Store 2) is normally distributed.
