psychologist would like to estimate the proportion of Americans that say "the future of the nation is a significant source of stress for me." To help form an estimate, the psychologist randomly selected 918 Americans and found that 69.7% of the sample agreed with the statement "the future of the nation is a significant source of stress for me." Using a 90% confidence level, determine the margin of error, EE, 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 90% confidence interval is given by=
