Question

A population has a mean μ=40 and a standard deviation σ=4. What is the standard deviation of the sampling distribution of the sample means if the sample size is n=16?

Answer #1

Solution :

Given that,

mean = = 40

standard deviation = = 4

n = 16

The sampling distribution of mean and standard deviation is ,

= **40**

=
/
n = 4 /
16 = **1**

A population has a mean μ=78 and a standard deviation σ=22. Find
the mean and standard deviation of a sampling distribution of
sample means with sample size
n=264.
μx= ?????

If a population is distributed with a mean μ and a standard
deviation σ, then the distribution of sample means is
distributed
A) normally with mean μ and standard deviation σ.
B) normally with mean μ and standard deviation σ/√(n).
C) with mean μ and standard deviation σ.
D) with mean μ and standard deviation σ/√(n).

The population has mean μ=29 and standard deviation σ=9.
This distribution is shown with the black dotted line.
We are asked for the mean and standard deviation of the
sampling distribution for a sample of size 34. The Central Limit
Theorem states that the sample mean of a sample of size n is
normally distributed with mean μx¯=μ and σx¯=σn√.
In our case, we have μ=29, σ=9, and n=34. So,
μx¯=29
and
σx¯=934‾‾‾√=1.5
This distribution is shown with the red...

Given the population mean, μ = 45, and the population standard
deviation, σ = 15 with a sample size of, n = 100.n = 100. Determine
P ( x ¯ ≤ 42 ). To do this problem first determine the sampling
mean and the sampling standard deviation in order to convert to a
z-score. Round your answer to 4 decimals.
