1. Susan Sound predicts that students will learn most effectively with a constantbackground sound, as opposed to an unpredictable sound or no sound at allShe randomly divides twenty-four students into three groups of eight. Allstudents study a passage of text for 30 minutes. Those in group 1 study withbackground sound at a constant volume in the background. Those in group 2study with noise that changes volume periodically. Those in group 3 studywith no sound at all. After studying, all students take a 10 point multiplechoice test over the material.

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
Company records indicate that less than 24% of employees commute to work using public transportation. You suspect this is incorrect and for a sample of 157 employees, and find that 18% of them take public transportation to work. Test the claim using a 10% level of significance. What is the p-value for this test?
A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts, Is this theory supported by the sample data? BB Click the icon to view the data table. Determine the null and alternative hypotheses. O A. Ho: The amount of smoking is dependent upon seat belt use. H₁: The amount of smoking is not dependent upon seat belt use. O B. Ho: Heavy smokers are not less likely than non-smokers to wear a seat belt. H₁: Heavy smokers are less likely than non-smokers to wear a seat belt. OC, Ho: Heavy smokers are less likely than non-smokers to wear a seat belt. H₁: Heavy smokers are not less likely than non-smokers to wear a seat belt. O D. Ho: The amount of smoking is independent of seat belt…
