A 99% confidence interval for μ: 134 to 161
(a) H₀: μ = 100 vs H_a: μ ≠ 100
(b) H₀: μ = 150 vs H_a: μ ≠ 150
(c) H₀: μ = 200 vs H_a: μ ≠ 200

A confidence interval for a sample is given, followed by several hypotheses to test using that sample. In each case, use the confidence interval to give a conclusion of the test (if possible) and also state the significance level you are using.
