Interval calculation

Expedia commissioned the second consecutive Airplane Protocol Research, in which 1000 Americans were asked to rank the most bothersome on-board passenger behaviors.

Backseat punts were voted the most annoying conduct by 67% of those polled. We calculate a 95% confidence interval and discover that the true population is between 0.029 and 0.67.

An appropriate interpretation of the stated interval is that between 63.2% and 70.8% of Americans would rank back seat kickers as the most unpleasant on-board behavior of fellow commuters.

Therefore, the final answer is "Option B".
