A population of values has a normal distribution with μ=104.4μ=104.4 and σ=5.3σ=5.3. You intend to draw a random sample of size n=16n=16.

What is the mean of the distribution of sample means?
μx¯=

What is the standard deviation of the distribution of sample means (i.e. the standard error)?
(Report answer accurate to 2 decimal places.)
σ¯x=

Solution :

Given that,

mean = = 104

standard deviation = = 5.3

n = 16

= 104

= / n

= 5.3 16

=1.325

= 1.32
