Out of a sample of 150 people who walked into a fast food restaurant, 135 said they prefer ketchup to mustard on their hamburgers. With 89% confidence, what is the confidence interval for the population mean of customers that prefer ketchup to mustard on their hamburgers? CI = (83.69%, 96.31) CI = (85.20%, 94.80%) CI = (86.09%, 93.91%) CI = (82.61%, 95.87%)
