For each of the following research questions, state the null and research hypotheses in words and in symbols; then determine the type of the hypothesis test. A national survey reported that children’s mean cholesterol level is 191 mg/dL. An investigator hypothesizes that cholesterol levels in children might be decreased by educating their parents on proper nutrition and exercise. A well-known pain medication is publicized to produce pain relief in 75% of patients within 30 minutes of taking the drug. A new pharmaceutical company claims that they have developed a new drug that produces pain relief in a larger proportion of people within 30 minutes.

For each of the following hypotheses, identify which statistical test we could run in order to address the specific research question being asked. Your options are: z-Test, One-Sample t-Test, Independent-Samples t-Test, and Paired-Samples t-Test. Be sure to mention a bit about the research design to explain why you chose that specific test: 1) Do the Dodgers and Giants differ in the number of strikeouts they have per game? 2) Does our stats class differ from the national average in IQ? 3) Do people perform better or worse on a cognitive task after they eat cookies? 4) Do “only children” drive safer than other children with siblings? 5) Do people have more friends in college than they did in high school? 6) Do people experience higher levels of sadness or anger after a specific negative outcome? 7) Do people remember information better if they hear it before or after lunch? 8) Are the players on my favorite basketball team shooting a better percentage than the league average?…
