Good video on statistical tests! But I find the answer statements rather confusing ;) In example 3, the claim is Ho. If one *fails to reject* Ho, that means he is NOT rejecting it, isn't that the same that he *accepts* Ho? I mean *fail to reject* == *accept*, isn't it? Something like this I understand much better: Is claim Ho? -> Yes -> Is Ho rejected? -> Yes -> claim is rejected Is claim Ho? -> Yes -> Is Ho rejected? -> No -> claim is accepted Is claim Ho? -> No -> Is Ho rejected? -> Yes -> claim is accepted Is claim Ho? -> No -> Is Ho rejcted? -> No -> claim is rejected
I realize this has been here for many years but--- t.y. I have worked on this problem #44 for 2 days, my mistake was not making and using L3-- and not knowing which < or > to use. It is a shame the wording of these problems are done so to purposely confuse a person, Saying to fail to reject is the same as not rejecting but accepting. Why would so many people spend so much time making it so confusing and not just being straight up--- kind of like telling lies--- the whole thing makes a person dislike this horrid class even more, and you know that is truth.
for number 2. You use the SET1-SET2 stating bigger number is Set1 but what is some of the data on SET1 were less than SET2 while some were greater. How do you decide? or is it never given like that?
Thanks so much! My statistic final today at 3pm, your video has taught me in two days how to use the TI-84 Plus calculator ... thanks a bunch!

Your videos are one of the main reasons I'm getting an A in my Statistics class. Thank you!
Thanks again, I give you the credit for my statistics grade. So much better than the college book/lecture!
Thank you for your videos, they are helping me so much with my stat class!
Thank you this saved me hours of doing it the long way
Thank you so much for providing such clear explanation video.
Love your videos , you are helping me to use my IT 84 Plus and providing greater understanding of Statistics. How do I submit questions to you?

A million Thank-Yous.
Thank youuuuuuuuuu!!!!

also what is alpha for the third question?
If alpha is not given, it is always assumed to be 0.05 (5%).
Thank you!!!!!!!!
@AGodboldMath Thank you so much! I'm taking my class online and tried to see how to complete it but it just says to use technology :D
These questions should be solved by using 2 sample t test. You made them all wrong. Go stat.....Test.....2sample t test
Thank you!!!!!!!!
