Question:

A reputable polling organization in a certain country surveyed 106,300 ​adults, and 18​% of those polled reported that they smoked.

1. Calculate the margin of error for the proportion of all adults who smoke with 99​% confidence.

ME = [ ]? Round to four decimals as needed


Answers

Ans:

given : n=106300 p = 0.18 q= 1-p = 0.82

Margin of error = Z * Sqrt ( p ( 1 - p) / n)

Z for 99% confidence is 2.576

Margin of error = 2.576 *sqrt(0.18*0.82 / 106300 )

= 0.00303
