D)0.0727

Question

Quizplus · Accepted Answer

The margin of error for a proportion is calculated using the formula: ME = Z * sqrt[(p̂(1-p̂))/n], where p̂ = x/n. For a 95% confidence interval, Z is approximately 1.96. Here, p̂ = 107/169. Calculate ME using these values to find it is approximately 0.0727.
