Instructor-created question IB Question According to a survey in a country, 34% of adults do not own a credit Suppose a simple random sample of 700 adults is obtained. Complete parts (e) below Click Here for StatCrunch (a) Determine the mean of the sampling distribution of (Round to two decimal places as needed.) (b) Determine the standard deviation of the sampling distribution 6.- (Round to three decimal places as needed.) (c) What is the probability that in a random sample of 700 adults, more than The probability is 17 (Round to four decimal places as needed.) Interpret this probability if 100 different random samples of 700 adults were obtained, one would expect result in more than 38% not owning a credit card. (Round to the nearest integer as needed.) (d) What is the probability that in a random sample of 700 adults, between 33% and 38% 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 700 adults expect to result in between 33% and 38% not owning a credit card. (Round to the nearest Integer as needed.) le) Would it be unusual for a random sample of 700 fewer who do not own a credit card? Why? Select the correct choice below answer box to complete your choice. (Round to four decimal places as needed.) O A The result is unusual because the probability than or equal to the sample proportions which is less than 5% B. The result is not unusual because the probab less than or equal to the sample proportion is which is greater than 5% OC. The result is unusual because the probability that is less equal to the sample proportion is which is greater than 5% OD.
