Normal Distribution Probabilities 

i have just tried to grasp this concept my entire 2 hour break and you just taught me it in 20 min thank you!!!

You did what my professor couldn't do in two weeks. She's still great but you my friend are greater. Keep up the good work! thanks

Very concise==clear and to the point-- Very good that you included a few different type examples--especially the use of the InvNorm key..

you wanna come take my ib calc test for me tomorrow?

Thank you! Taking Statistics online and your video helped so much!

Thank you soooooo much !!! May God shine his light upon you sir for all eternity ! 😃

You explain this a lot better than my teacher does, thanks for the upload!

THank you sir, This video just boosted my probability to not fail a stastics exam coming up LOL

You Sir, are awesome!

You are such a life saver

thank you, how do you find a z-score less than a certain number example less than 1.28 or greater than 1.28?

to express infinity you would use the small e which is the second command for the comma and then you would add 99

Supper useful thank you so much!

JUST want to build a LIVE STAGE somehow don't know how many people fittings in?

Thanks a lot sir.

THIS WAS VERY HELPFULL

Thank you!!!!
