    one sample t test between percents




    if I have two percentages say

    50% and 10% from a survey conducted with 20 people

    and there are 3 possible answers yes, no and don't know

    50% answered yes and 10% answered no how do you work out if the difference is significant.

    I have searched all over and cant find something that fits

    thanks

    If you want to know whether the proportion of "yes"
    is significantly larger than the proportion of "no"
    (leaving out don't know), then you can perform a
    binomial test with expected roportion 0.50 .

    With kind regards

    thanks so much. maybe should have explained more so I am looking to prove that the higher percentage of yes didn't happen by chance? will the binomial test do this? thanks again
