Using the information in Question #6, what decision should the researcher make regarding the null hypothesis?

Reject the null hypothesis.

What will the researcher in Question #1 conclude?

Reject the null hypothesis; students in their final semester experience significantly greater anxiety than students in their first semester.

In the scenario described in Questions #6-#9, the researcher can only conclude that the two means are different. If they reject the null hypothesis, they still cannot conclude which group has a higher mean because it is a two-tailed test.

false

Using the information in Question #1, the obtained t-statistic is:

not 1.98
