In a 1363 paper, German physician Carl Wunderlich reported based on over a million body temperature readings that the mean body temperature for healthy adults is 93.5\"\" 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. 93.0, 93.41 93.5, 93.1 31?, 93.2, 93.0, 9?.6 {it} Find the value of the test statistic. Eh} Find the 1% critical value. (d) 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?(A) One-sample z-test for a population mean. (B) check to see if the answer in (a) is less than the answer in (b). (C) Draw a normal probability plot, and see if the points fall close to a straight line. (D) Check to see if the p-value in (c) above is greater than .10. (E) check to see if the answer in (a) is greater than or equal to the answer in (b). (F) Check to see if the p-value in (c) above is less than the a value. (G) Draw a normal probability plot, and see if the points are bell-shaped (like the normal curve). (H) One-sample t-test for a population mean
