Suppose you are testing the hypothesis h_0: mu_d = 0 and h_a: mu_d ! = 0 in a paired-design and obtain a p-value of 0.02. also suppose you computed confidence intervals for mu_d. based on the p-value, which of the following is true? select one: a. a 95% confidence interval will contain 0, but a 99% confidence interval will not. b. a 95% confidence interval will not contain 0, but a 99% confidence interval will. c. both a 95% confidence interval and a 99% confidence interval will contain 0. d. neither a 95% confidence interval nor a 99% confidence interval will contain 0.
