A coffee shop franchise owner is looking at two possible locations for a new shop. To help make a decision 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 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 347 and a sample standard deviation of 85. Assume the two populations variances are not known but are equal. Calculate the pooled estimate of o O 10362.42 O 101.80 O 22.40 O 503.32

-6-7 Let A = 3 5. Find 4A.
