Question 1187130
pJ=0.52
pP=0.48
Ho:they are equal
Ha: they are not equal
alpha=0.05 p{reject Ho|Ho true}
test stat is a z
critical value for rejection is |z|>1.96
pooled proportion is 152/300=0.507
z=(0.52-0.48)/sqrt(0.507(0.493)(1/200)+(1/100))
=0.04/0.0612
z=0.65 fail to reject; insufficient evidence to say the two proportions are different.
p-value =0.51
