Ho: p = .25
\n" ); document.write( " Ha: p ≠ .25
\n" ); document.write( " -----------------------------------------
\n" ); document.write( " sample proportion = p-hat = 111/500 = 0.222
\n" ); document.write( " ---
\n" ); document.write( " test stat:: z(0.222) = (0.222-0.25)/sqrt[0.25*0.75/500] = -.028/.0194
