Using a random sample of 4,000 students, you decided to compute a 95% confidence interval to estimate the mean calories consumed by the students. A colleague decided to compute another 95 confidence interval using a different sample, this time with only 1,000 students. What change woul you expect from the first confidence interval to the second. A The margin of error will be twice as wide.
