A certain survey conducted had a population proportion of at most 22% for people who agreed. What is the confidence level if 20% of the people sampled agreed, and the standard error of the proportion is ±1%?

Question

jim_thompson5910 · Answer

well if it's plus/minus 1 percent, then it sounds like the confidence interval would be 20 - 1 = 19% to 20+1 = 21%

jim_thompson5910 · Answer

in short, the confidence interval would be (19%, 21%)

or (0.19, 0.21)
