You collect a random sample of size n from a population and calculate a 98% confidence interval. Which of the following strategies produces a new confidence interval with a decreased margin of error?
Use a 99% confidence level.
Use a 95% confidence level.
Decrease the sample size. (not correct)
Use the same confidence level, but compute the interval n times. Approximately 2% of these intervals will be larger.
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 0.02.
