According to the above two-way contingency table, do we have enough evidence to conclude that ages is not related to seat-belt usage at 10% significance level?

The National Center for Drug Abuse is conducting a study to determine if the heroin usage among teenagers has changed. Historically, about 1.3 percent of teenagers have used heroin one or more times. In a recent study of 1800 teenagers, 35 said they had used heroin one or more times. Is there significant evidence that heroin usage among teenagers has changed? What concerns do you have about this data?

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? Number of Cigarettes Smoked per Day 0 1–14...
