Question 1191809
Ho: p1=p2
Ha: p1 NE p2
test stat is 2 sample proportion 
critical value is |z|>1.645
p total is 19/40=0.475
calculation z=(p1-p2)/sqrt  pt(1-pt) (1/n1)+1/n2)}
=-0.05/sqrt {0.475*0.525{2/20)]
=-0.3166
Fail to reject Ho p-value is 0.76, double the probability of the z-value because 2-way test.
This is greater than 0.10.
