An experimental drug is being tested to see if it reduces blood sugar in patients suffering from diabetes. Each of seven patients will receive both the placebo and the experimental drugs (treatments given a month apart) for a two week period. The maximum blood sugar (measured every day) on the second week of treatment is recorded. The data obtained from such a study is shown below:
| patient | placebo | exp.drug | difference |
| 1 | 125 | 127 | -2 |
| 2 | 130 | 100 | 30 |
| 3 | 133 | 110 | 23 |
| 4 | 122 | 87 | 23 |
| 5 | 150 | 102 | 48 |
| 6 | 156 | 140 | 16 |
| 7 | 145 | 146 | -1 |
| mean | 137.3 | 116 | 21.3 |
| SD | 13.1 | 22.1 | 18.5 |
Conduct a hypothesis test to determine whether the new
experimental treatment is beneficial for treating
diabetes.

Question: 9 hypertension patients in a clinic use an
experimental drug for treatment. The systolic blood pressure
reading for these patients before and after using the drug are as
follows:
Assume that blood pressure has a standard deviation of 5 mmHg.
Do you think the drug works?

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 2 hours after taking the drug are shown in the table
below. Is there enough evidence to support the company's claim? Let
d = (blood pressure before taking new drug) − (blood pressure after
taking new drug). Use a significance level of α = 0.05 for the
test. Assume that the...
