Question

The accompanying table lists body temperatures from 68 different randomly selected subjects measured at two different times in a day. Assume that the paired sample data are simple random samples and the differences have a distribution that is approximately normal. Complete parts (a) and (b) below. Click the icon to view the data on body temperatures. a. Use a 0.05 significance level to test the claim that there is no difference between body temperatures measured at 8 AM and at 12 AM. In this example, ?d is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the temperature at 8 AM minus the temperature at 12 AM. What are the null and alternative hypotheses for the hypothesis test? H0: ?d °F H1: ?d °F (Type integers or decimals. Do not round.)
