    can anyone tell me how to find the critical value

  • @LadyVenVen
    @LadyVenVen 2 года назад

    This still makes no sense to me because every example I see everyone gets a different result. So how do I know who’s doing it correctly? You’re explanation was very detailed I just still don’t understand how everyone does the “rejection if t is not” step differently.”

    Good video. I was wondering about the critical value with respect 5% significance level mentioned in the first example. I think the value is -1.96 for one tailed test. The critical value with 10% significance level is 1.64. You have mentioned 1.64 for both the examples. Correct me if am wrong. Thank you

    Great video! Like and subscribed. How did you find -1.645? I can’t seem to find it in the z table. Thank you

    • @whatsupdude2778
      @whatsupdude2778  2 года назад +1

      Thanks for the support. -1.645 is actually between the values of -.164 and -1.65, so, it is not specifically listed in the table. This will happen sometimes when you are doing these types of problems. I should have mentioned that in the video, sorry, my bad on that.

    have u covered binomial distribution sir, in any of your videos?

    • @whatsupdude2778
      @whatsupdude2778  2 года назад +2

      Yes, I have 2 videos on that, I will link them below. The first is the binomial distribution, and the second is a normal approximation to the binomial distribution. I will also put a third link to a stats playlist of 82 statistical videos I have posted, that will make it easier for you to find specific topics you may have an interest in.

    and i think the critical value should be 1.960 not 1.645, plz correct me if iam wrong

    • @astral6413
      @astral6413 5 месяцев назад

      It's 1.645, you were looking at the two tails but the problem only requires the one tail.

  • @AbhishekShuklaAbK
    @AbhishekShuklaAbK 3 года назад

    Critical value should have been -1.29, no? -1.30+0.01 = -1.29
