You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 99% confident that the sample percentage is within 3.5 percentage points of the true population percentage.

1,355 air passengers must be surveyed

Step-by-step explanation:

Note that the population proportion is not stated in the question, it will be assumed to be 50%. i.e. p = o.5

Error Margin, E = 3.5% = 0.035

Confidence Level, CL = 90% = 0.99

Therefore, Significance Level,

At ,
