^ azine provided results from a poll of 2000 adults who were asked to identify their favorite pie. Among the 2000 dents, 11% chose chocolate pie, and the margin of error was given as ±3 percentage points. What values do p, E, and p represent? If the confidence level is 95%, what is the value of a? value of p is value of q is value of n is e value of E is e value of p is more help. 3 Clear all Check answer

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 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
