A random sample of n = 1200 observations from a binomial population produced x = 689.
\n" ); document.write( "p-hat = 689/1200 = 0.5742
\n" ); document.write( "z(0.5742) = (0.5742-mean)/std
\n" ); document.write( "Comment:: Insufficient information to calculate the mean and std.
\n" ); document.write( "------------
