Market research team members design a study aimed at estimating the proportion of customers who will accept the service agreement changes. 1. At the confidence level (= C 0.90), determine the SMALLEST sample size needed for the margin of error no higher than B 3.5% 2. At the confidence level (= C 0.95), determine the SMALLEST sample size needed for the margin of error no higher than B = 4.5% 3. What will be the largest margin of error for a 95% interval based on n= 100 records?
