    Big thanks from Nepal. Your contents are really awesome. Please keep posting more videos related to statistics. My college teacher is so bad at teaching this, due to which I had lost interest on this subject but from your videos, I think stat is not as hard as I thought. Thankyou so much again. Your channel will surely become popular one day. Best wishes !

    Sir, i have a doubt. in case of left tailed test, Z(alpha) is negative.. and while comparison we always take |Z| which is positive. means |Z| will always be greater than Z(alpha) leading to out null hypothesis always wrong. What to do in that case. I have been following your statistics series from the start. and I forgot to text this on your previous video so I am doing in this one. please clarify this

    • @HamKan
      @HamKan 2 роки тому +3

      Proportion is 5:3 males:females
      that is if there are 5 males , there will be 3 females
      if there are 5x males, there will be 3x females
      Total number of people will be
      5x+3x = 8x
      Now, we want to find the proportion that is the % of females, therefore it will be number of females / total number of people
      = 3x/5x+3x =
      3x/8x = 3/8 = 0.375

      See at 23.32. Because wholesaler is claiming that not more than 4% apple are defective. ( since his claim says that 4% or less are defective )
