Question

A drawer contains 4 capsules numbered 1, 3, 5, and 7. A sample of size 2 is drawn with replacement. What is the standard deviation of x-bar?

a) 1.24

b) 1.58

c) 1.66

d) 1.75

Answer 1

Answer #1

We know that Standard deviation of x-bar is given by:

Now, n = 2

and

So, standard deviation =

Hence option B is the correct option.
