After one month, people in both groups were asked to report if the pill they took...

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 null hypothesis? Note: All...

Suppose that a pharmaceutical company claims that it has a new cure for the flu, and that %96 of flu sufferers will fully recover within 24 hours of taking the drug. As a first test on the claim, a clinic will give the drug to 25 people diagnosed with the flu and check on their condition 24 hours later. Suppose that company’s claim is perfectly accurate. 1. Let random variable X be the number of people tested who will recover...
