A random sample is selected from a population with mean and standard deviation . Determine the mean and standard deviation of the sampling distribution of for each of the following sample sizes: a. n = 9
b. n = 15
c. n = 36
d. n = 50
e. n = 100
f. n = 400

a. Mean = 100, S.D. = 3.333

b. Mean = 100, S.D. = 2.582

c. Mean = 100, S.D. = 1.667

d. Mean = 100, S.D. = 1.414

e. Mean = 100, S.D. = 1

f. Mean = 100, S.D. = 0.5

Step-by-step explanation:

The question is incomplete:

Population mean: 100

Population standard deviation: 10.

The mean for any sampling distribution is equal to the population mean.

The standard deviation for the sampling distribution depends on the population standard deviation and the sample size as:

We can calculate the parameters of the sampling distributions as:

a. n = 9

b. n = 15

c. n = 36

d. n = 50

e. n = 100

f. n = 400

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
