could u show me steps plz. thx

In a 1868 paper, German physician Carl Wunderlich reported based on over a million body temperature readings that the mean body temperature for healthy adults is 98.6\" F. However, it is now commonly believed that the mean body temperature of a healthy adult is less than what was reported in that paper. To test this hypothesis a researcher measures the following body temperatures from a random sample of healthy adults. 98.2, 98.4, 98.5, 985,914, 98.4 (a) Find the value of the test statistic. (I1) Find the 1% critical value. (c) Q Work through this examp on R, and then use R to nd the p-value for the relevant hypothesis test. ((1) Since the sample size is less than 30, the above analysis requires that the population follows a normal distribuiton. What method could be used to check this assumption? |:| test statistic (correct to 4 decimals) |:| critical value (correct to 3 decimals) |:| p-value (A) One-sample ttest for a population mean. (B) Draw a normal probability plot, and see if the points are bell-shaped (like the normal curve). (C) One-sample z-test for a population mean. (D) check to see if the answer in (a) is greater than or equal to the answer in (b). (E) Check to see if the p-value in (1:) above is greater than .10. (F) Check to see if the p-value in (c) above is less than the 0. value. (G) check to see if the answer in (a) is less than the answer in (b). (H) Draw a normal probability plot, and see if the points fall close to a straight line. d}: What method
