A random sample of size n = 200 yielded p = 0.20. a. Is the sample size large enough to use the large sample approximation to construct a confidence interval for p? Explain. A. No, because np 2 15 and nq< 15. В. Yes, because np 2 15 and nq 2 15. O C. No, because np< 15 and nq < 15. O D. No, because np < 15 and ng < 15. b. Construct a 99% confidence interval for p, the population proportion. The 99% confidence interval for p is (,). (Round to two decimal places as needed.)
