    I'm taking an online summer stats class and out of the dozen I've tried watching none have been as clear as this. Having the text on the screen and referencing as you go helps a ton for my learning style, thanks again!

    Thank you for making this so easy to do on the calculator. I was lost trying to figure out how my teacher was coming up with these random p values.

    Good tip at 6:20 ... saves you time counting and recounting to make sure you've written the number with the correct number of zeros after the decimal point.

    Hello! thank you so much for this by the way! You are sent from heaven !
    Just one question though. Would this table work with t test or hypothesis prop testing? Sorry might be stupid question. I am just barely learning all of this.
    thanks again!

    Can you please confirm? There's different answers/videos all over RUclips about when to use T-est and when to use Z-Test..The only time you can use a T-Test is when the Distro is normal (or approx) and "Population" Standard Deviation is UNknown? What happens if N

      I'm sure this answer is way too late after 3 years, but this is a proportion problem (0.70 out of 1.00) and the video is about mean problems. Maybe taking note of this will help someone else.
