hey got wrong answer still

A manager of a small store wanted to install signs around the store saying, “Shoplifting is a crime!” However, she wanted to make sure this would not affect sales. To test whether the signs would affect how much the customers purchased, she displayed the signs every other Wednesday for 8 weeks, for a total of 4 days displayed. She recorded the store’s sales for those four Wednesdays, then recorded the store’s sales for the four alternate Wednesdays, when the signs were not displayed. On the Wednesdays with the sign, the mean level of sales was 79 with a standard deviation of 4.32. On the Wednesdays without the sign, the mean level of sales was 85 with a standard deviation of 3.46. Do these results suggest that customers' purchasing is affected when the signs are displayed? Use the .05 significance level. (Hint: pooled variance estimate = 15.34). What cutoff score(s) should be used? ±2.036   ±2.447   +1.943    –1.860
