A current antacid provides relief for 71% of the people who use it. A pharmaceutical company has a new drug and they want to test whether it is more effective. They run a study with 100 randomly selected patients and 72 people experienced relief. Is this evidence that the new drug is more effective? Use the p-value method with significance level α = 0.01.

A pharmaceutical company is testing a new drug. Of the 110 people that received the drug, 61 of the people's autoimmune disease went into remission. Using the old drug, the autoimmune disease for 50% of all the people treated went into remission. When testing whether or not the new drug is more effective than the old drug at treating people's autoimmune disease (in terms of the percentage of cases going into remission), what would be the alternative hypothesis? Note: All...

The manufacturer of a new antidepressant claims that, among all people with depression who use the drug, the proportion p of people who find relief from depression is at least 80%. A random sample of 205 patients who use this new drug is selected, and 160 of them find relief from depression. Based on these data, can we reject the manufacturer's claim at the 0.05 level of significance? Perform a one-tailed test. Then fill in the table below. Carry your...

A pharmaceutical company introduced a new drug that would reduce cholesterol levels. A researcher selected 10 cholesterol patients and tested them for their cholesterol level. The subjects were then placed on the new drug for a period of 6 months, and the cholesterol level reading was taken again. Both the results are given below. Assume the samples are random and dependent, and the populations are normally distributed. Use 0.01 level of significance and test whether there is evidence of reduced...

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 22 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=0.01 for the test. Assume that the systolic blood pressure levels are normally...

In 2005, a study was conducted to compare two treatments for people who experienced a stroke. In Salt Lake City, 450 patients were assigned randomly to one of the two treatments: 220 to treatment 1 and 230 to treatment 2. A total of 74 patients survived the stroke: 35 in the group receiving treatment 1 and 39 in the group receiving treatment 2. A test of significance was conducted on these hypotheses: H0: The survival rates for the two treatments...
