On the Hypothesis Example II, when listing your data in the calculator you mentioned that in the section that looks like u1:, you should make it look like your alternative hypothesis, but you made it not equal to, instead of making it look like the alternative hypothesis you wrote u1<u2.

I thought for proportions you have to use a combined p-hat value in the calculations and when checking for normality? The equation for it is (x1+x2)/(n1+n2)

Hey, Mrs. Nelson!This is Heather. I am using the review book 5 steps to a 5 for self-learning. And I was really confused about which tests I should use because on the book, the author kinda just jumbled all the stuff together.. BUT! Your "Pick Your Test" Map is such a brilliant idea and it helps me tremendously! I just want to say thank you so much! :) Have a great day!Heather
