When nothing is known about the percentage of persengers who prefer aisle seat, we make use of p = 50% = 0.5.
Thus,

Therefore, 1,537 </span><span>randomly selected air passengers must be surveyed to </span><span>be 95% confident that the sample percentage is within 2.5 percentage points of the true population percentage.
Part B:
Given that recent surveys surgest that about 38% of all air passengers</span> prefer an aisle seat, thus p = 38% = 0.38
<span>Thus,

Therefore, 1,449 </span>randomly selected air passengers must be surveyed to <span>be 95% confident that the sample percentage is within 2.5 percentage points of the true population percentage.</span>
