Let's examine the relationship between CI's and hypothesis tests:
Hint: you need to think about how/when confidence levels and hypothesis tests are equivalent. In
particular, what happens to a CI as you change the confidence level?
(a) You calculate a 99% confidence interval for μ and come up with (10,26). If you test H0: μ = 7 and
use α = .01, will you reject H0? Why or why not?
(b) Now you calculate a 95% CI for μ and come up with (-5, -1). If you test H0: μ = 3 and use α = .10,
will you reject H0? Why or why not?
(c) Finally, you calculate a 95% CI for for μ and come up with (-24,-8). If you test H0: μ = - 13 and use α = .01, will you reject H0? Why or why not?
