Oh! well thats an easy one Julia!


The normal model is only useful when the sampled values are independent of each other, and the sample size (n) is large enough.

Before using the Normal model, we must check that the randomization, 10%, and success/failure conditions are present...



How sad. i'm replying to my own posts...

Julia is so smart! Now you're not the only one replying to your posts! I agree with everything that you said. I think you said it all. What can I add to your brilliance? Well, to make sure that the sample size is large enough, we must make sure that both n x p and n x q are both greater than or equal to 10. 8D
