Let's examine the relationship between CI's and hypothesis tests:
(a) You calculate a 90% confidence interval for μ and come up with (-10, 26). If you test H0: μ = 27 and use α = .10, will you reject H0? Why or why not?
(b) Now you calculate a 95% CI for μ and come up with (3, 7). If you test H0: μ = 9 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 (-34, -28). If you test H0: μ = - 27 and use α = .01, will you reject H0? Why or why not?
Could explain how to proceed with this question please?
