Question 417897
Let P1 be the proportion of successes in the first population and let P2 be the proportion of successes in the second population. 
Testing:
H0: P1-P2=0
HA: P1-P2≠0 
Suppose z*=1.73 
how do we find the p-value for the test to 4 decimal places?
=====
It's a 2-tail test so
the p-value = 2*P(z > 1.73) = 0.0836
