This is a two-part question on margin of error and theconfidence interval. I am unable to determine the calcuation to solve thisproblem. Problem: a study based on a sample of size 25 reported a meanof 93 with a martin of error of 11 for 95% confidence. (a) Give the 95% confidence interval. (b) If you wanted 99% confidence for the same study, wouldyour martin of error be greater than, equal to, or less than11? Help me to explain how to calculate.
