Question 1169719
J=0.12
S=44/255=0.1725
The difference between them is 0.0525
doing a 2 sample proportion
half-interval for 90%CI is 1.645* sqrt[(0.12*0.88/125)+(0.1725*0.8275/255)], sqrt term=0.0374
=0.0617
The 90% CI is difference+/- the half-interval 
(-0.1142, 0.0092)
Because 0 is in the interval, we can be 90% confident that there is no significant difference between these two proportions. Stated another way, if they were part of the same population, these samples could occur by chance.
