    Excellent!
    Ho: MrNystrom =Other Stat Professors
    Ha: MrNystrom (is better that) > Other Stats Professors
    Reject Ho
    Accept Ha: MrNystrom is 100% better that other stats professors

    I have learned more from you in the few videos that I have watched than I have learned from my two, yes I said two (in the same classroom!), Stats professors at my university!

    One week before my final, and I wish I'd been watching these since week 1. You have a really clear instructing method. Thanks for these videos!

    It just clicked!!!! I watched this 3-4 times over the last few days, and filled-in the 'gaps', by watching his other videos, working problems, and reading the text. But, Mr.Nystrom knows how to reach people on a different level. THANK YOU!!!!!!
    I have a chance at passing my Stats class now..and keeping my job;)

    How this guy is so hyped about beats me but god bless his enthusiasm cause this finally clicked. Now whenever I try to explain something to myself I have @MrNystrom in my head. You got to make more content!

    Best teaching method with focus is solely on the understanding the concept rather tons of information. Your fun way of teaching makes this otherwise boring subject and interesting one. :-)

    Thank you dude for all your videos. I can't deal with reading my book, I am not absorbing it but your videos are amazing. I keep referring to them in my posts for my Statistics class to help other people too that don't learn from books. Ignore any haters on here. Keep doing what you are doing. I love that you move around a lot and get close to the camera. Keeps my attention and I don't zone out. lol

    Yelling it like it is actually gets into my ADHD brain sooooo much more effectively than all the bazillion other put-me-to-sleep versions of the topics you explain, Mr. Nystrom. I also love how you always add extra golden nuggets of info just a little beyond the topic(s) in your titles --- your videos have been helping me achieve results in my test scores and understanding --- I Can't Thank You Enough!!!

    Wait, is the alternative hypothesis given in the problem like the null hypothesis, or do you make it up? If you make it up, then what is the basis for your HA? How do I decide if I want to say "proportion of kids who like cheese has increased" or "proportion of kids who like cheese has decreased"?
