What is the P-value for the testing of the following hypothesis for someone who gets 25 right out of 100? 30 right? 35 Right? 50 right?
\n" ); document.write( "The null hypothesis is p=.2 that a person is guessing in an ESP experiment where one person randomly draws one of 5 cards and the \"reciever\" person tries to determine which card it is. The alternative hypothesis is p>.2 is to show support that the person is doing better than guessing.
\n" ); document.write( "------------------------
\n" ); document.write( "Ho: p=0.2
\n" ); document.write( "Ha: p>0.2
\n" ); document.write( "--------------
\n" ); document.write( "If p-hat = 25/100 = 0.25
\n" ); document.write( "then z(0.25)= (0.25-0.20)/[sqrt[(0.2*0.8/25)] = 0.05/0.04/5 = 5*0.05/0.04
\n" ); document.write( "= 0.625
\n" ); document.write( "The the p-value associated with this z value is 0.266
\n" ); document.write( "--------------
\n" ); document.write( "Do the same for p-hat = 30/100, then p-hat=35/100, the p-hat=50/100
\n" ); document.write( "=========================
