A coffee shop franchise owner is looking at two possible locations for a new shop. To help him decide, he looks at the number of pedestrians that go by each of the two locations in one-hour segments. At location A, counts are taken for 35 one-hour units, with a mean number of pedestrians of 421 and a sample standard deviation of 122. At the second location (B), counts are taken for 50 one-hour units, with a mean number of pedestrians of 347 and a sample standard deviation of 85. Assume the two populations variances are not known but are equal. Testing the claim that both sites have the same mean number of pedestrians at α = .01, what do you conclude?
