Obtaining a driver's license at the earliest eligible age has been a teenage ritual that appears to be fading. A study performed by a university's transportation research institute recently found that 29% of U.S. teenagers between the ages of 17 and 19 did not possess a driver's license. A random sample of 125 17-to-19-year-old teenagers was selected. Complete parts a through d. a. What is the probability that 45 or fewer teenagers of this sample had not obtained a driver's license The probability is N. (Round to four decimal places as needed.) b. What is the probability that 50 or more teenagers of this sample had not obtained a driver's license? The probability is (Round to four decimal places as needed.) c. What is the probability that between 35 and 40 teenagers had not obtained a driver's license? The probability is O (Round to four decimal places as needed.) d. Suppose that 29 teenagers from this sample had not obtained a driver's license. Does this result support the findings reported by the university's transportation research institute? Consider a probability of less than 0.05 to be small. Select the

Transcribed Image Text:Obtaining a driver's license at the earliest eligible age has been a teenage ritual that appears to be fading. A study performed by a university's transportation research institute recently found that 29% of U.S. teenagers between the ages of 17 and
19 did not possess a driver's license. A random sample of 125 17-to-19-year-old teenagers was selected. Complete parts a through d.
a. What is the probability that 45 or fewer teenagers of this sample had not obtained a driver's license
The probability is N
(Round to four decimal places as needed.)
b. What is the probability that 50 or more teenagers of this sample had not obtained a driver's license?
The probability is N.
(Round to four decimal places as needed.)
c. What is the probability that between 35 and 40 teenagers had not obtained a driver's license?
The probability is
(Round to four decimal places as needed.)
d. Suppose that 29 teenagers from this sample had not obtained a driver's license. Does this result support the findings reported by the university's transportation research institute? Consider a probability of less than 0.05 to be small. Select the
correct choice below and fill in the answer box to complete your choice.
(Round to four decimal places as needed.)
O A. The results do not support the claim because the probability of finding a sample proportion at least as extreme as the one found is which is greater than 0.05.
O B. The results do support the claim because the probablity of finding a sample proportion at least as extreme as the one found is which is less than or equal to 0.05.
O C. The results do support the claim because the probability of finding a sample proportion at least as extreme as the one found is which is greater than 0.05.
O D. The results do not support the claim because the probability of finding a sample proportion at least as extreme as the one found is which is less than or equal to 0.05.
