1. State the null hypothesis, alternative hypothesis and identify the claim for each conjecture a. A medical researcher is interested in finding out whether a new medication will have undesirable effects on patients pulse rates. Since she knows that the mean pulse rate for the population under the study is 82 beats per minute, the hypotheses for this situation are: b. A contractor wishes to lower heating bills by using a special type of insulation in houses. If the...

The following numbers are the differences in pulse rate (beats per minute) before and after running for 12 randomly selected people. Positive numbers mean the pulse rate went up. Test the hypothesis that the mean difference in pulse rate was more than 0,using a significance level of 0.05. Assume the population distribution is Normal 22,8,11,12,15,7,0,2,9,39,1, and 13 Determine the null and alternative hypotheses.
