Suppose samples of size 100 are drawn randomly from a population that has a mean of 20 and a standard deviation of 5. What are the values of the mean and the standard deviation of the distribution of the sample means

a) The mean of the sampling distribution of means μₓ = μ = 20

b) The standard deviation of the sample σₓ⁻ = 0.5

Step-by-step explanation:

Explanation:-

Given sample size 'n' =100

Given  mean of the Population 'μ' = 20

Given standard deviation of population 'σ' = 5

a) The mean of the sampling distribution of means μₓ = μ

                                                                                     μₓ = 20

b) The standard deviation of the sample σₓ⁻   =    

    Given standard deviation of population 'σ' = 5

                                                                              =

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
