So I have this weird math question, that I don't think gives enough information.
Find the standard deviation of the sample proportion for a sample of size 150, when we assume equal probabilities for the wins and losses of a football tournament. Assume also, that the number of outcomes in the population ( N) is very large, essentially infinite.
So I know that finding the standard deviation using sample proportions would be: sq root: pq/n, meaning the equation would be:
square root of: (the mean*(1-mean)/150 )
How would I compute the standard deviation with equal probabilities while the population is infinite?
These are the potential answers:
a. 0.12
b. 0.50
c. 0.002
d. 0.25
e. 0.041
