Testing the Assumed s In the example included in this section, we rejected H0: m 5 98.6 and supported H1: m 2 98.6 given the assumption that s 5 0.62 and the sample data consist of n 5 106 values with 5 98.20.

a. What aspect of this example is not realistic?

b. Find the largest value of s that results in the same conclusion that was reached assuming that s 5 0.62.

c. Given that the 106 body temperatures have a standard deviation of 0.62, is there any reasonable chance that the true value of s is greater than the value found in part (b)? What does this imply about the assumption that s 5 0.62?
