We make decisions every day. In making decision, we usually follow certain processes andthen make an appropriate interpretation or choice. This is the essence when we conducthypothesis testing to validate our claim and make a better decision in life. As a wise Columbanite,choose a problem in your community that you can use the process of hypothesis testing. Make ascenario out of it using all the data needed in hypothesis testing, then cite your claim about thisproblem. Use samples that are less than 30. Lastly test your claim if it is true. Show your step bystep process in conducting hypothesis testing based on what you learned on this module. Keepyour data, it might be needed in the future lesson.

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.
