Finding a Critical Value for Critical Region in the Right

Tail
Using a significance level of α = 0.05 find the critical z value for the alternative hypothesis : H1 : p > 0.5 (assuming that the normal distribution can be used to approximate the binomial distribution). This alternative hypothesis is used to test the claim that the XSORT method of gender selection is effective, so that baby girls are more likely, with a proportion greater than 0.5.
