A normal distributed population has parameters μ=112.2 and σ=23.9. If a random sample of size n=98 is selected,

What is the mean of the distribution of sample means?
μ¯x=
What is the standard deviation of the distribution of sample means? Round to two decimal places. to find answer
σ¯x=

Solutions

Expert Solution

Solution :

Given that ,

mean = = 112.2

standard deviation = = 23.9

n = 98

sample distribution of sample mean is ,

= 112.2

sampling distribution of standard deviation

= / n = 23.9 / 98

= 2.41
