You can put this solution on YOUR website!
p = 450/600 = 3/4, q = 1/4
ME = z%2Asqrt%28%28p%281-p%29%29%2Fn%29
77% confidence level: z = invNorm(.77 + .115) = invNorm(.885) = 1.2

ME = ±1.2%2Asqrt%28%28%283%2F4%29%281%2F4%29%29%2F600%29 = highlight%281.2%29 *.0177 = .02124 0r 2.1%
If these are Your choices... 2.5,2.4,3.4, and 5.4
Might Check z (highlighted)
77% ??? confidence level Haven't seen that before....
