You can put this solution on YOUR website! Suppose we test the difference between two proportions at the 0.05 level of significance. If the computed z is -1.07, what is our decision?
p-value = 2*P(z<-1.07) = 2*normalcdf(-100,-1.07) = 0.2846
----
Since the p-value is greater than 5%, fail to reject Ho.
