  1. There is a new type of drug to alleviate migraines but some have wondered if it has some impact on users’ blood pressure. Ten people interested in taking the drug were randomly selected and their blood pressure was measured, and then measured again after using the drug five weeks later. Here are the data. Was there a significant change in blood pressure? Use a two-tailed test with α = .05 (t-Table is on p. 439).

A clinical trial is conducted on a specific drug used to treat severe migraines and it is noted that approximately 25% of individuals in the study fail to respond to the drug and the medication appears to give them severe episodes of nausea and vomiting. Upon further examination it is revealed that these individuals carry a genetic marker, and the individuals who did not experience the side effects of nausea and vomiting did not have the same marker as those...

Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a random sample of males and females, the following question: “Are you annoyed by people who repeatedly check their mobile phones while having an in-person conversation?” Among the 571 males surveyed, 192 responded “Yes” among the 549 females surveyed, 206 responded “Yes”. Does the evidence suggest a higher proportion of females are annoyed by this behavior? A. Determine the sample proportion...

The Food and Drug Administration (FDA) is asked to approve a new drug. The new drug should contain less than 25mg of the active ingredient “toxin”, which is assumed to have dangerous side effects. The FDA would like to restrict the error of “approving the drug despite its too high content of toxin” to a maximum risk of 5% (α ≤ 0.05). Let Xi : “ The content of toxin in the i-th pill [in mg].” ∼ N(µ, σ2 )...
