n is the sample size
\n" ); document.write( "p is the population proportion
\n" ); document.write( "p-hat is the sample proportion
\n" ); document.write( "Use the Central Limit Theorem to find the Proportion probability.
\n" ); document.write( "n = 101, p = 0.86, P (p-hat < 0.80)
\n" ); document.write( "------
\n" ); document.write( "z(0.80) = (0.80-0.86)/sqrt[0.86*0.14/101] = -1.7378
\n" ); document.write( "----
\n" ); document.write( "P(p-hat < 0.8) = P(z < -1.7378) = normalcof(-100,-1.7378) = 0.0411
\n" ); document.write( "========================
