An educational software company wanted to see if students improved their entrepreneurial skills after participating in five rounds of their game.

The students were scored on a numerical scale. A higher score is better. They found the difference in the ratings by finding d = pre-post. What is the appropriate alternative hypothesis? Ha: d_bar < 0 O Ha: mu_d < 0 Ha: d_bar0 O Ha: mu_d>0
