Let X have a Binomial distribution with the number of trials n=15 and with probability of "success" p. We wish to test Ho: p=0.30 vs. H1: p doesn't equal 0.30.
Reject Ho if the likelihood ratio <= 0.15. Find the significance level.
I know that if the likelihood ratio <= 0.15, then that means X<=1 or X>=9. The significance level is P(Reject Ho | Ho true) but I can't figure out how to find that. Any help would be appreciated.
