Assuming that my null hypothesis is that males and females are equally likely to sign up for a stats course, my alternate hypothesis is that the probability of males signing up is 0.3, alpha is set at 0.05 and n is 25. i need to find the critical value of y as well as beta, how do i do this i am so stuck?

\n" ); document.write( "Well, that's a bit confusing.
\n" ); document.write( "If Ho is p(m)-p(f) = 0
\n" ); document.write( "then Ha should be p(m)-p(f) is not 0
\n" ); document.write( "-----
\n" ); document.write( "It appears that a sample 25 people was taken and 30% of them were males.
\n" ); document.write( "Based on alpha being 5% and the fact that you are doing a 2-tail test,
\n" ); document.write( "the critical values are z = +-1.96.
