Devon's tennis coach says that 72% of Devon's serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon's serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon's hypotheses are H o p = 72% and H a p > 72%, where p = the true proportion of Devon's serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using a= 0.05, what conclusion should Devon reach? Because the P-value of 0.06 > a, Devon should reject Ha. There is convincing evidence that the proportion of serves that are good is more than 72%. Because the P-value of 0.06 > a, Devon should reject H a. There is not convincing evidence that the proportion of serves that are good is more than 72% Because the P-value of 0.06 > a Devon should fail to reject H o. There is convincing evidence that the proportion of serves that are good is more than 72%. Because the P-value of 0.06 > a Devon should fail to reject H o. There is not convincing evidence that the proportion of serves that are good is more than 72% ​
