U = mean
Where u = 8000; standard deviation = 1000 and x = the amount of votes to pass.
1 - .907 = .093
9.3%
The votes needed for passage of the controversial … is 9,322 which is
Between 1 and 2 standard deviations …
9,000 < x < 10,000
2000/1,322 = 1.528
1.528 standard deviations is approximately 90.7 % and therefore to get the result you have to subtract form 1.000 therefore you get
1-.907 = .093 or approximately 9.3 %
