A police officer claims that the proportion of drivers wearing seat belts is more than 55%. To test this claim, a random sample of drivers are checked for seat belt usage. Assume that the test statistic for this hypothesis test is 1.87. Assume the critical value for this hypothesis test is 1.645. Come to a decision for the hypothesis test and interpret your results with respect to the original claim.
Select the correct answer below:
a. Fail to reject the null hypothesis There is not enough evidence to support the claim that the proportion of drivers wearing seat belts is more than 55%.
b. Reject the null hypothesis There is enough evidence to support the claim that the proportion of drivers wearing seat belts is more than 55%.
