It is commonly believed that the mean body temperature of a healthy adult is 98.6° F. You are not entirely convinced. You believe that it is lower than 98.6° F. The temperatures for 14 randomly selected healthy adults are shown below. Assume that the distribution of the population is normal. 95.4, 95.6, 100.7, 94.8, 99.1, 96, 95.2, 99.5, 100.3, 97.1, 99.9, 96.6, 97.2, 95.9 What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? O Select an answer C Ha: ? O Select an answer © (please show your answer to 3 decimal places.) c. The test statistic ? = d. The p-value = e. The p-value is ? a f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) There is not sufficient evidence to conclude that the population mean body temperature for healthy adults is equal to 98.6° F. There is not sufficient evidence to conclude that the population mean body temperature for healthy adults is lower than 98.6° F. There is sufficient evidence to conclude that the population mean body temperature for healthy adults is lower than 98.6° F.
