    this really helped me and it was so much better than my teacher's attempt to teach this to my class, thank you

      Glad it helped and thanks for the feedback, Ive learnt a bit more video editing so future videos should be even better and produced more nicely

    in a two tailed test how would you find the actual significance level if there is more than one critical value?

    • @SachchitP
      @SachchitP  3 роки тому +1

      Hi Dylan - so it would be the same way you do so for a one tailed test, you just treat each of the tails as their own separate one.
      Step 1 ) find probability for lower tail using table or calculator
      Step 2 ) find probability for upper tail using table or calculator
      Step 3) add them together
      I'm assuming by more than one critical value you meant the upper and lower tails in a two tailed test. Lmk if that makes sense, if not I can give you a more detailed example.

    How can you think the die is fair and unfair at the same time?

    • @SachchitP
      @SachchitP  3 роки тому

      Hey Ashley - what it means to say is we assume the die is a fair dice (but we suspect that it may be unfair and want to test for it). Usually when hypothesis testing, this is the assumption we will make !
