You collect a random sample of size n from a population and calculate a 90% confidence interval. Which of the following strategies would produce a new confidence interval with an increased margin of error? Use an 80% confidence level. Use the same confidence level, but compute the interval n times. Approximately 10% of these intervals will be larger. Use an 85% confidence level. Decrease the sample size. 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 0.10.
