Answer #1

We know that the % confidence interval for population mean is given by:

Width of the interval =

a) Width of the interval =

b) Width of the interval =

c) Width of the interval =

e) Width of the interval =

So, the width for part (b) is minimum.

Hence 2nd option is the correct option.
