    Spent an hour reading the notes and trying to figure this out, then I searched for it on RUclips, found this awesome video and understood it in less than 15 minutes. Thanks for the great video!

    If it is a 2 tailed test then use the P(xbar > or < value) based on whether or not xbar is less than or greater than u. (less than u, means P(xbar < value) and opposite for greater than u)

    is it written X bar N(mean, (standard deviation)squared, divide by n) or is the squared squaring both the standard deviation and the n ? so (standard deviation/ n ) squared. Thank you in advance

    It's hard to tell if the xbar ~ N(mu, 6²/n) or if the 6 is sigma

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  2 года назад

      For the CIE exam board, you'll need to know how to conduct hypothesis testing for Binomial and Poisson Distributions.

      I think it is fair to politicise maths especially for normal distribution as it makes it easier to understand. Analogies are useful and maths is used everywhere.

      Though , it would've been better to use another analogy (not coronavirus) as this topic can be sensitive to some people... just saying, but you did use other examples too anyway. Thanks examsolutions for your content, I have been making use of your channel as my exams are coming up, it has been helpful.
