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
