Hi,
I made a survey to n people asking their sign (12 signs were available).
A number k answered Libra. I want to analyze this result. But I'm not
sure if I'm doing it right. First I assume:
p = 1/12
q = 1 - p
Then the Binomial probability is:
PROB = nCk * p^k * (1-p)^(n-k)
The Binomial Test is:
z = (k/n-p)/sqr(p*q/n)
and the Chi-Squared is:
X^2 =(k - p * n) ^ 2 / (p * n) + ((n - k) - q * n) ^ 2 / (q * n)
Am I right?
I'm not sure about the value of p in the Binomial Test (should it be = PROB?), and if the Chi-squared can be calculated like that.
Kind regards,
Kepler
