You are the operation manager for an airline and you are considering a higher fare level for passengers inside soats. How many randomly selected air passengers must you survey that you want to be 99% confident that the sample percentage is within 2.5 percentage points of the true population percentage. Complete parts (a) and (b) below.

could you reply to this with the question so i can ?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
