On average, a person's body temperature should be approximately 98.6°F. A doctor would like to test the hypotheses Ho: 98.6 versus H 98.6 where μ = the true mean body temperature of all adults. A 99% confidence interval based upon a random sample of 100 adults is (97.5, 99.2). Using the interval, can the researcher reject the null hypothesis? OYes, the null hypothesis can be rejected at the significance level a = 0.01, because 98.6 is contained in the 99% confidence interval. Yes, the null hypothesis can be rejected at the significance level a = 0.005, because 98.6 is contained in the 99% confidence interval. O No, the null hypothesis cannot be rejected at the significance level a = 0.01, because 98.6 is contained in the 99% confidence interval. No, the null hypothesis cannot be rejected at the significance level a = 0.005, because 98.6 is contained in the 99% confidence interval.
