I see. I wanted it not to be boring since you can always pause. Thanks for the feedback though.

How dud you get .16?
@joshemman Жыл бұрын
At 0:46, q = 1 - 0.84 = 0.16
@veerakanneboina8086 5 ай бұрын
there are two critical values +1.88 and -1.88. Buy why only 1.88 is taken in the calculation
@joshemman 5 ай бұрын
Because there's already +/- in the formula.
@veerakanneboina8086 5 ай бұрын
So, the +/- in the Confidence interval formula accounts for the positive and negative critical values.@@joshemman
@veerakanneboina8086 5 ай бұрын
So, +/- in the formula accounts for +Z_(alpha/2) and -Z_(alpha/2) @@joshemman
