Let μ denote some population mean of interest and suppose a 95% confidence interval for μ is calculated to be (0.63, 0.73) and a 99% confidence interval for μ is calculated to be (0.61,0.75). Also, suppose that we want to test H0: μ = 0.74 vs. Ha: μ ≠ 0.74 What can you say about the corresponding p-value? Choose from following letters.  a. The corresponding p-value will be smaller than 0.05 but larger than 0.01. b. The corresponding p-value will be larger than 0.05. c. I can’t say anything about the corresponding p-value until I run the test.
