"Randomly selected A recent campaign was designed to convince car owners that they should fill their tires with nitrogen instead of air. At a cost of about $5 per tire, nitrogen supposedly has the advantage of leaking at a much slower rate than air, so that the ideal tire pressure can be maintained more consistently.  Before spending huge sums to advertise the nitrogen, it would be wise to conduct a survey to determine the percentage of car owners who would pay for the nitrogen.  How many randomly selected car owners should be surveyed? Assume that we want to be 98% confident that the sample percentage is within three percentage points of the true percentage of all car owners who would be willing to pay for the nitrogen. My work: (2.29)^2 x (.25)/(.03^2)=1457 but the correct answer is 1509.  " eNotes Editorial, 28 July 2010, https://www.enotes.com/homework-help/randomly-selected-186485. Accessed 27 Jan. 2023.
