Human oral normal body temperature is believed to be 98.6° F, but there is evidence that it actually should be 98.2° F [Mackowiak, Wasserman, Steven and Levine, JAMA (1992, Vol. 268(12), pp. 1578-1580)]. From a sample of 52 healthy adults, the mean oral temperature was 98.285 with a standard deviation of 0.625 degrees. (a) What are the null and alternative hypotheses? Ho:μ = 98.2and H₁ :μ > 98.2 Ho: 98.2and H₁:μ< 98.2 O Ho:μ = 98.2 and H₁ :μ # 98.2 (b) Test the null hypothesis at a = 0.05. Find to. Round your answer to two decimal places (e.g. 98.76). to = i Is it possible to reject Ho hypothesis at the 0.05 level of significance? Yes. No.
