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
