A random sample of size n = 100 yielded p=0.80. a. Is the sample size large enough to use the large sample approximation to construct a confidence interval for p? Explain. b. Construct a 90% confidence interval for p. c. Interpret the 90% confidence interval. d. Explain what is meant by the phrase "90% confidence interval." b. The 90% confidence interval for p is (.). (Round to two decimal places as needed.) c. Interpret this confidence interval. A. We are confident that 90% of the population is described by the interval for p. B. There is a 90% chance that the value of p is outside the interval. O C. We are confident that 90% of the population is outside the interval for p. O D. We are 90% confident that p lies in the confidence interval. d. Explain what is meant by the phrase "90% confidence interval." O A. The confidence interval is within 10% of the true parameter value. O B. 90% of similarly constructed intervals would be centered on the true value of the parameter. C. There is a 90% chance that the true value of the parameter is the midpoint of the interval. O D. 90% of similarly constructed intervals would contain the true value of the parameter.
