Question
According to a survey in a country, 23% of adults do not have any credit cards. Suppose a simple random sample of 700 adults is obtained.
(a) Describe the sampling distribution of p, the sample proportion of adults who do not have a credit card. Choose the phrase that best describes the shape of the sampling distribution of p below.
O A. Not normal
O B. Approximately normal
Determine the mean of the sampling distribution of p.
HA = (Round to two decimal places as needed.)
Determine the standard deviation of the sampling distribution of p.
(Round to three decimal places as needed.)
(b) A certain town believes their residents are less likely to own credit cards. They take a random sample of 700 adults in their town. They find a sample proportion of .17. What is the probability of getting 17 or less?
The probability is (Round to four decimal places as needed.)
Would this be considered unusual?
