Using the same sample data given in problem 1, test the claim that the standard deviation of body temperatures for normal healthy adults is less than 1.00 C. Use a 0.05 level of significance. 3. Use a 0.05 level of significance to test Bill Bradley's claim that the majority of voters would vote for him.
