A researcher surveyed a random sample of 1,151 people from a certain state to estimate the percentage of people who support the governor’s recent approval of a bill. From the survey, the researcher estimated that 67% of people from the state support the governor’s approval of the bill, with an associated margin of error of 2.37%. The researcher repeated the survey with a random sample of people from the state that was double the original sample size. Assuming the margins of error were calculated in the same way, which of the following is true about the margin of error associated with the estimate from the larger sample?
