  • @BreakerByte Thanks, I've actually viewed the entire playlist. The answer dawned on me basically as soon as I answered the question, but thanks anyway. I need to get through the probability playlist as well though

  • Am I the only one that thinks that donating money to KhanAcademy would be a better spent tithe?

  • @MixTheMeister

    check out the whole playlist on statistics, he explains this in a previous video.

  • This question has popped up several times when I've been watching these videos. Why can you say that μx = μ = p

    I agree that μx would approximate μ = p depentent on the size of the n. Wouldn't rather be μx ≈ μ = p?

  • Great like always Sal,

    i was just thinking about what if you post under downloads of the khanacademy home page just the screenshots from Paint of all yours videos. In that way i think we could have a quick preview of all the Info in that lecture and we would not always need to play the whole video when just refreshing the memory ;) . I hope you get it what i mean. You are just great!!! Thanks a lot !

  • Great 

  • EXCELLENT WORK =)
