Problem 3. (15 points) A franchiser was interested in determining how many vehicles, on average, pass by the proposed location of a restaurant on a hourly basis. Suppose the standard deviation of the number of vehicles passing by the proposed site of the restaurant is = 18.8. In order for the location to be financially viable, the mean number of vehicles passing by the proposed location per hour has to be at least 141. If it is less than 141 the franchiser will not believe the location viable. The statistical hypotheses is Ho:}=(2)141 HAH? 141 (a) If the sample average, X, is found to be less than 138.3 the franchiser will not believe the location viable. The number of vehicles passing by this location is to be observed in each of 99 randomly chosen one-hours, and X then computed from these data. m= Calculate a. (use at least four decimals in your answer) (b) If a Type I error was not made, what would happen?. Correctly complete the statement below. ? V A Type I error would not occur if one concluded that the mean number of vehicles pass by the proposed restaurant location is ? vehicles passing by this location per hour is when in fact the mean number of - (c) The sample of n = 99 one-hours was taken. The mean number of vehicles passing by the proposed location of the restaurant was found to be X = 137.3. From these data what should the franchiser do? ? the restaurant, because the null hypothesis is to be ? (d) From the information provided in part (c), compute the P-value.
