An article in IEEE International Symposium on Electromagnetic Compatibility quantified the absorption of electromagnetic energy and the resulting thermal effect from cellular phones. The experimental results were obtained from in vivo experiments conducted on rats. The sample mean and sample standard deviation arterial blood pressure values (mmHg) for the control group (8 rats) during the experiment are ?̅? = ??, ?? = ? and for the test group (9 rats) are ?̅? = ???, ?? = ??. Is there evidence to support the claim that the test group has higher mean blood pressure?

(a) State the null and alternative hypothesis, the test statistic, and the critical region.

(b) Do the data support the claim that the mean blood pressure from the test group is at least 15 mmHg higher than the control group? State the null and alternative hypothesis, the test statistic, and the critical region.

    An article in IEEE International Symposium on Electromagnetic Compatibility (Vol. 2. 2002, pp. 667- 670) describes the quantification of the absorption of electromagnetic energy and the resulting thermal effect from cellular phones. The experimental results were obtained from in vivo experiments conducted on rats. The arterial blood pressure values (mm Hg) for the control group (8 rats) during the experiment are mean = 90, 51 - 5 and for the test group (9 rats) are mean2 = 115 and s2...

    Loretta, who turns 91this year, has heard that the mean systolic blood pressure among the elderly is 120 millimeters of mercury (mmHg), but she believes that the actual value is higher. She bases her belief on a recently reported study of 22 randomly selected, elderly adults. The sample mean systolic blood pressure of the adults in the study was 131mmHg, and the sample standard deviation was 22 mmHg. Assume that the population of systolic blood pressures of elderly adults is...

    A pharmaceutical company believes its Alzheimer’s drug may have an effect on cortical atrophy. If it decreases cortical atrophy, it may be a promising candidate for further drug trials; if it increases cortical atrophy, it may provide insight into the mechanism of Alzheimer’s disease. Thus the company decides to test the drug on rats, as either result may hold future benefits. Among 115 transgenic rats (genetically engineered to induce Alzheimer’s), 65 rats receive the drug over 6 months, 50 rats...
