It is commonly believed that the mean body temperature of a healthy adult is 98.6 F. A medical student is not entirely convinced, and believes that it is not 98.6 F. To test this belief, she collected data using a random sample of 20 healthy people and found that they had a mean body temperature of 98.33 degrees with a standard deviation of 1.14 degrees. Use an or = 0.05 significance level to test the claim that the mean body temperature of a healthy adult is not 98.6 F. a) Identify the null and alternative hypotheses? Ho: ? v H1: ? b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O two-tailed O left-tailed O right-tailed c) Identify the appropriate significance level. d) Calculate your standardized test value. Write the result below, and be sure to round your final answer to two decimal places. t = e) What is the critical value? Give three decimal places. to f) What is the result of the test? We reject the null hypothesis and accept the alter
