The Department of Motor Vehicles in a small suburban community noted that 28% of people who take their driving test at their facility fail the first time. They would like to lower this failure rate and decide to develop a supplemental study pamphlet to help new drivers learn and remember the rules. They randomly sample 70 new drivers and find that when given the supplemental study pamphlet before their driving test, only 11 out of the 70 (16%) participants failed. After running a z of proportion test statistic, the researchers find a p-value of .02. Which definition of a p-value is the most accurate? The probability that the alternative hypothesis (that the study pamphlet will lower the failure rate) is true is .02. The probability that the observed result (16%) will happen again is .02. The probability that the observed result (16%) or a result more extreme will occur if the null hypothesis is true is .02. The probability that the null hypothesis (that the study pamphlet will not change the existing failure rate of 28%) is true is .02.
