Using the same scenario as in question 3 (restated below), answer the following question: A manager of a small store wanted to discourage shoplifters by putting signs around the store that said, "Shoplifting is a crime!", while at the same time making sure the signs would not reduce the number of sales. To test the effect on sales, the signs were displayed every other Wednesday for 8 weeks, and the numbers of sales for those four Wednesdays were 83, 73, 81, and 79. The numbers of sales for the four alternate Wednesdays without the sign were 84, 90, 82, and 84. Using the results provided, tell me if the results were significant: With Sign: N = 4; df = 3; M = 79; S2 = 18.67 No Sign: N = 4; df = 3; M = 85; S2 = 12.00 Cutoff score (t needed) = +/-1.943. t = -2.17 Are you results significant? Were sales affected? Select one: a. Yes, the t score is significant. The sign does affect sales. b. No, the t score is not significant. The sign does not affect sales.

t = -2.17
Are you results significant? Were sales affected?
Yes, the t score is significant. The sign does affect sales.
No, the t score is not significant. The sign does not affect sales.
