How dud you get .16?

[@joshemman]

At 0:46, q = 1 - 0.84 = 0.16

[@veerakanneboina8086]

there are two critical values +1.88 and -1.88. Buy why only 1.88 is taken in the calculation

[@joshemman]

Because there's already +/- in the formula.

[@veerakanneboina8086]

So, the +/- in the Confidence interval formula accounts for the positive and negative critical values.@@joshemman

[@veerakanneboina8086]

So, +/- in the formula accounts for +Z_(alpha/2) and -Z_(alpha/2) @@joshemman

[@joshemman]

@@veerakanneboina8086 yes.
