A coffee shop franchise owner is looking at two possible locations for a new shop. To help make a decision the owner 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 and 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 247 and a sample standard deviation of 85. Assume the two populations variances are not known but are equal, and that the number of pedestrians is approximately normal.
-Provide a one-sentence interpretation of the 95% confidence interval for the mean difference in pedestrian traffic at the two locations.
