In a popular painkiller medicine, it is advertised there is 500 mg of the active ingredient per pill. The amount of active ingredient per pill follows a normal distribution with a mean of 506 mg and a standard deviation of 2 mg. What is the probability that a single pill of the painkiller contains less than 500 mg of active ingredient? (Use a table or technology. Round your answer to four decimal places.)

In a clinical study of an allergy drug, 108 of the 203 subjects reported experiencing significant relief from their symptoms. Using a significance level of 0.01, test the claim that more than half of all those using the drug experienced relief. State the null hypothesis H0. State the alternative hypothesis H1. What is the test statistic? State the alpha level. Determine p value. Do you or do you not reject the null hypothesis? Why? Write a clear conclusion using a...

The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.05 level that the medicine relieves pain in less than 371 seconds. For a sample of 12 patients, the average time in which the medicine relieved pain was 368 seconds with a standard deviation of 20. Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. Step 2 of 5: Find the...

4. Long-lasting drugs: One of the ways in which doctors try to determine how long a single dose of pain reliever will provide relief is to measure the drug's half-life, which is the length of time it takes for one-half of the dose to be eliminated from the body. A report of the National Institutes of Health states that the standard deviation of the half-life of the pain reliever oxycodone is o=1.43 hours. Assume that a sample of 25 patients...
