Researchers want to know if a new drug works faster than Advil at reducing headaches. They believe that it will reduce headaches in an average of 10 minutes, rather than the 30 minute average for Advil. They recruited 50 people for their experiment. • They matched up two people with similar characteristics. • When the subjects got a headache one took Advil and one took the new drug. • They then compared the amount of time it took to reduce headaches. • At the end of the study they found that the new drug reduced headaches in an average of 12 minutes rather than an average of 28 minutes for Advil. What does the 12 minutes represent? Sample Proportion Sample Mean Population Proportion Population Mean

The manufacturer of an over-the-counter medication, Tylenol, claims that its product brings pain relief to headache sufferers in less than 3.5 minutes, on average. In order to be able to make this claim in its television advertisements, the manufacturer was required by a particular television network to present statistical evidence in support of the claim. The manufacturer randomly selected 50 headache sufferers and discovered that the mean time to relief was 3.3 minutes and the standard deviation was 1.1 minutes. Using the 5-step process developed in class, do headache sufferers receive relief in less than 3.5 minutes? Use a significance level of 0.05. What type of error might have been committed? Can the manufacturer run the ad?

The Excellent Drug Company claims that its aspirin will relieve headaches faster than any other aspirin on the market. To determine whether Excellent's claim is valid, 30 volunteers who are suffering from headaches are randomly assigned to 2 groups of 15. The subjects in one group are given Excellent's aspirin, and the subjects in the other group are given aspirin from the Simple Drug Company. The number of minutes required for each subject to recover from the headache is recorded. The Excellent aspirin had a mean of 8.4 minutes with a standard deviation of 4.23. The Simple aspirin had a mean of 8.9 minutes with a standard deviation of 1.19. Test the claim for the Excellent Drug Company. A) State the hypotheses. B) Find the P-value to the nearest thousandth. C) State the conclusion in the context of the problem.

"A particular drug company claims that its headache medicine stops the headache in 14 minutes or less. Being skeptical, you randomly selected 25 headache patients and asked them to take those pills. The time (min) it took for the headache to disappear is recorded and the result is as follows: mean time = 19 min; s-7 min. Do the results of your studies reinforce or disagree with the drug company's claim?"
