Question 1177082: The proportion of eligible voters in the next election who will vote for the incumbent is assumed to be 52.3%. What is the probability that in a random sample of 600 voters, less than 49.8% say they will vote for the incumbent?
Probability =
I got the result 0.1112 but it tells me that it is wrong.

Hi
z+=blue+%28x+-+mu%29%2Fsqrt%28blue%28p%281-p%29%2Fn%29%29

z+=blue+%28.498+-+.523%29%2Fsqrt%28blue%28.523%28.477%29%2F600%29%29 = -1.2260

P(z < -1.2260) = normalcdf(-9999,-1.2260, 1, 0) = .1101

Wish You the Best in your Studies.
