Please check the math on the calculations. 2.672 x 4.4 / sqrt(54) = 1.599, round to 1.60. 22.5 +/- 1.60 = 20.90 to 24.10.
You're right. I'll put a note about the error. Thanks.
Why it is taken only alpha/2 in upper tail, why can't it be from alpha/2 of lower tail of the distribution
The explanations are not clear😢
they are very clear indeed
