Question

Hi, not sure how to go about doing this hypothesis test. Would appreciate any help. thanks!

tudy was concerned with the effects of anxiety on test performance. It was theorized that
very anxious people might not only show a lower average performance relati
peers but als
showing normal general ability but high test-anxiety was taken. Each student was given a simple
mathematics test. In general, the scores of college students on this test follow an approximatey
normal distribution, with a mean of 55 and a standard deviation of 6. The sample of anxious
ve to their nonanxious
o a higher degree of variability in performance. A random sample of 22 college students
students had a mean of 51 and a standard deviation s 10. Test both of the hypotheses implied
here, using α- 05 for each.
