Suppose you collect a SRS of size n from a population and from the data collected you computed a 95% confidence interval for the mean of the population. Which of the following would produce a new confidence interval with larger width (larger margin of error) based on these same data? A. Use the same confidence level, but compute the interval n times. Approximately 5% of these intervals will be larger. B. Use a larger confidence level. C. Use a smaller confidence level. D. Nothing can guarantee absolutely that you will get a larger interval. One can only say the chance of obtaining a larger interval is 0.05. E. None of the above.
