Question 981815
This is a two sample proportion test
Ho=proportions equal
Ha=proportions not equal.
alpha=0.05 
test statistic;;  z= [(phat1-phat2)-(p1-p2)]/sqrt{ ((p1)*(1-p1)/n1))+ ((p2)(1-p2))/n2)}
Critical value abs(z)>1.96
on the calculator
phat1=0.0447; p2hat=0.0234
z=2.38
Reject Ho; there is a difference.
