HI Eugene, just a quick message to thank you for these great videos. They are clear, well ordered, well built and nicely presented. Honestly, this is so much clearer than notes that can be given by universities... Thanks a lot!

It would be nice if you can make another video to clearly show when you set the alpha value to 0.05, and also test with 0.01.
