    at 07:58 the equation will be I think P(X^2 is greater than 6) is less than 10% as per the chi-square distribution table

      I think he just assumed/rounded that it's greater than 10% instead of saying something like greater than 9.85% or so

    • @calintimbus7876
      @calintimbus7876 5 лет назад +4

      Even so this number is higher than 0.05%

    Shouldn't the p value be less than 10% for getting greater than 10%

  • @jaycee9153

    Why are we allowed to obtain the p-value from a chi-square distribution?

    I did not get why the null hypothesis is not rejected.

    • @4kChannel

      because the p of .1 is greater than .05, our alpha value

    We can only reject the Null hypithesis. Are you sure we can accept something?? Or we can test for rejection or not rejection?

    How did you get the actual #? I understand everything else, just not sure how you got that number.

      by conducting a sample
      it will usually be provided for u in the exam

    No, it doesn't make any sense for me till there will be explanation why chi squared has exactly this formula.

    Why not, instead of continuously adding new videos, add practice activities for existing courses?
    If I wanted to watch RUclips vids there are plenty of more engaging channels :(
