Question:
The residents of Austin, Texas, complain that parking fines given in their city are higher than the parking fines that are given in Houston. Independent random samples of the amounts paid by residents for parking tickets in each of two cities over the last four months were obtained. Assume the population variances are equal. These amounts were as follows:
Austin | 80 | 125 | 144 | 98 | 138 | 100 | 129 | 113 | 132 | 115 |
Houston | 98 | 85 | 114 | 100 | 76 | 85 | 120 | 105 | | |

A) 78.30
B) 97.88
C) 117.40
