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
26 males and 20 females. The males took an average of 3.7 English courses with a standard
deviation of 0.3. The females took an average of 3.6 English courses with a standard deviation of 0.6.
Conduct a hypothesis test at the 1% level of significance to determine whether the means are
statistically the same.
Step 1: State the null and alternative hypotheses.
Ho: 12V0
Ha: 1₂ VO
