You collect a random sample of size n from a population and calculate a 95% confidence interval. Which of the following strategies produces a new confidence interval with an increased margin of error? A. Use a 98% confidence level.
B. Use a 90% confidence level.
C. Increase the sample size.
D. Use the same confidence level, but compute the interval n times. Approximately 5% of these intervals will be larger.
E. Nothing can guarantee that you will obtain a larger margin of error. You can only say that the chance of obtaining a larger interval is 0.05.
