In the leаd-up tо the 2024 U.S. electiоns, а nаtiоnwide poll was conducted one month before election day to measure public support for Issue 1.

Then, compute and report the width of the confidence interval and margin of error. (Report all values rounded to two decimal places). lower endpoint = [BLANK-1], upper endpoint = [BLANK-2] width=[BLANK-3], margin of error = [BLANK-4]
