This question is on the relationship between confidence intervals and hypothesis testing. Suppose, you wish to use a random sample to conduct the one-sample two-sided t-test for the mean and test the following hypotheses: H0: μ = 98.5 vs. H1: μ ≠ 98.5, at the significance level of 0.01. The 99% confidence interval for the mean calculated by using this sample is [85, 97]. Based on this confidence interval your decision will be (choose one answer): Accept H0 Reject H0 None of the above
