Question

Question 5 13 01 Details 15.3. You intend to draw a random sample of A population has parameters u = 109.2 and o = size n = 135. What is the mean of the distribution of sample means? What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) 02

Answer 1

Solution :

Given that,

The sampling distribution of mean is ,

$\mu$_{$\bar x$} = 109.2

The sampling distribution of standard deviation is ,  

$\sigma$_{$\bar x$} = $\sigma$ / $\sqrt$ n = 15.3 / $\sqrt$ 135 = 1.32
