You have the best explanation for question 5d ❤❤❤❤❤

So far, for every video of yours that I have watched because I couldn’t understand how to do a question, you explained so incredibly well and in such a logical manner, that I’m genuinely amazed. Maths is a little less scary, now!

Thank you <3

after looking to the marking scheme, bro did wrong in question 2, it's a two tailed test not a one tailed test

Hello your video is amazing I was just wondering for question 4 part B couldn’t why isn’t there a combination like 10 and 80 or 20 and 60

at 24:09, could you possibly do inverse normal instead and set the area to 0.95? then you would get a mean value of 11.47, but I don't understand how this could lead to the conclusion that we accept H1, because I thought the mean would have to be greater than 11.5. Is this method incorrect?
