Question

I'm having such a hard time understanding this problem and I got it wrong 2 times. It would help if someone could explain or show me how to solve it.

The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The
males took an average of four English courses with a standard deviation of 0.7. The females took an average of five English courses with a standard deviation of 1.1. Are the means statistically the same? (Use a = 0.05)
NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
