To help form an estimate, the psychologist randomly selected 917 Americans and found that 73.2% of the sample agreed with the statement "the future of the nation is a significant source of stress for me." Using a 98% confidence level, determine the margin of error, E and a confidence interval for the true proportion of all Americans that say the "the future of the nation is a significant source of stress for me." Report the confidence interval using interval notation Round solutions to four decimal places, if necessary. The margin of error is given by E = A 98% confidence interval is given by
