It is commonly believed that the mean body temperature of a healthy adult is 98.6∘F98.6∘F. You are not entirely convinced. You believe that it is not 98.6∘F98.6∘F. You collected data using 49 healthy people and found that they had a mean body temperature of 98.28∘F98.28∘F with a standard deviation of 1.05∘F1.05∘F. Use a 0.05 significance level to test the claim that the mean body temperature of a healthy adult is < 98.6∘F98.6∘F. a) Identify the null and alternative hypotheses? H0: HA: c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to 3 decimal places.
