Suppose a simple random sample of size n 200 is obtained from a population whose size is N 320,000 and whose population proportion with a specified characteristic is p 30.2 (a) Describe the sampling distribution of p. Choose the phrase that best describes the shape of the sampling distribution below OA. Approximately normal because n S0.05N and np(1-p) 10 B. Approximately normal because n s0.05N and np i p) 10. C. Not normal because n S 0.05N and np -p 10 (1 OD. Not normal because n S0.05N and np -p) 2 10. (1 Determine the mean of the sampling distribution of p- HA Round to one decimal place as needed.)

Solution

a) Option B

b) Mean of sampling distribution = 0.2
