According to a survey in a country, 16% of adults do not own a credit card. Suppose a simple random sample of 500 adults is obtain. A.) describe the sampling distribution of P the sample proportion of adults is obtained. A.) Determine the standard deviation of the sampling distribution of P. B.) what is the probability that in a random sample of 500 adults more than 15% do not on a credit card? C.) if 100 different random samples of $500 for a team one would expect what to result in more than 17% not only a credit card? D.) Would it be unusual for a random sample of 500 adults to result in 60 or fewer do not on a credit card why? Is it unusual or not unusual because the probability of P is less than or equal to the sample proportion is what?, which is less than 5%
