From part c we know that there are significantly different success rates for the students with different goals. It is evident that those with high expectations do better. To test the null hypothesis of no relationship between sex and major use the chi-squared procedure. Reject Ho, there is a relationship between gender and major b. In words, males are more likely to major in finance and ccounting than females.
Females are more likely to major in administration c.
Many more females than expected and many fewer males than expected in administration if there were no relationship between major and gender. Only 225 females and 161 males responded. All are satisfied here. The observed difference could be due to chance so we can't conclude that there is a significant difference. In fact, this difference does persist in larger samples and would be significant if samples were large enough.
