![According to a survey in a country, 38% of adults do not own a credit card. Suppose a simple random sample of 300 adults is obtained. Complete parts (a) through (d) below.
(c) What is the probability that in a random sample of 300 adults, between 35% and 40% do not own a credit card?
The probability is [ ].
(Round to four decimal places as needed.)
Interpret this probability.
If 100 different random samples of 300 adults were obtained, one would expect [ ] to result in between 35% and 40% not owning a credit card.
(Round to the nearest integer as needed.)
(d) Would it be unusual for a random sample of 300 adults to result in 105 or fewer who do not own a credit card? Why? Select the correct choice below and fill in the answer box to complete your choice.
(Round to four decimal places as needed.)
- A. The result is unusual because the probability that \( \hat{p} \) is less than or equal to the sample proportion is [ ], which is less than 5%.
- B. The result is unusual because the probability that \( \hat{p} \) is less than or equal to the sample proportion is [ ], which is greater than 5%.
- C. The result is not unusual because the probability that \( \hat{p} \) is less than or equal to the sample proportion is [ ], which is greater than 5%.
- D. The result is not unusual because the probability that \( \hat{p} \) is less than or equal to the sample proportion is [ ], which is less than 5%.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77f69c35-8558-4881-b631-6923950412ef%2Fbaa723e3-51fe-4a2d-bd7c-b16f0d10eb63%2Fq2p255j_processed.png&w=3840&q=75)
