I collect a random sample of size n from a population and from the data collected compute a 95 confidence interval for the mean of the population Which approach would produce a new confidence interval with smaller width smaller margin of error based on these same data O A Use the same confidence level but compute the interval n times Approximately 5 of these intervals will be larger OB Nothing can guarantee that you will get a smaller interval One can only say the chance of obtaining a smaller interval is 0 05 OC Use a smaller confidence level D Use a larger confidence level
