An experiment was conducted to test the ability of rats to navigate a maze, as measured by the time it takes rats to find food at the end of the maze.
The maze completion times (in minutes) for 25 male and 28 female rats were observed, with the results given below.
| Male | Female | |
| Mean | 64.19 | 56.85 |
| StDev | 13.845 | 13.747 |
Calculate a 95% confidence interval for the difference (males - females) in average maze completion times and choose the correct answer. Use df = n1 + n2 - 2.
