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%

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
