(d) Would it be unusual for a random sample of 900 adults to result in 144 or fewer who do not own a credit card? Why? Select the correct choice below and fill in the answer box to completeyour choice.(Round to four decimal places as needed.)O A. The result is not unusual because the probability that pless than or equal to the sample proportion iswhich is greater than 5%.O B. The result is unusual because the probability that p is less than or equal to the sample proportion iswhich is greater than 5%.O C. The result is unusual because the probability that p is less than or equal to the sample proportion iswhich is less than 5%.OD.The result is not unusual hecause the nrohahility that n is less than or equal to the sample nronortion iswhich is less than 5%% According to a survey in a country, 18% of adults do not own a credit card.
