Among 2178 passenger cars in a particular region, 244 had only rear license plates. Among 356 commercial trucks, 48 had only rear license plates. A reasonable hypothesis is thatcommercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.

Identify the null hypothesis, alternative hypothesis, test statistic, P -value, conclusion about the null hypothesis, and state the final conclusion that addresses the original claim in non-technical term. A certain type of bolt used for installing the doors of Honda Civic cars is supposed to have a mean diameter of 15 mm. An engineer claims that a recent change of suppliers may result in a change of the diameter of this bolt. To test this claim, a random sample of 100 bolts were chosen, and it was found that the sample had a mean diameter of 15.3 mm, with a sample standard deviation of 1.8 mm. Use a 0.05 level of significance to test his claim. Use the P-value method of testing hypotheses. State the final conclusion in a non-technical way.
