If all the possible random samples with n = 36 scores are selected from a normal population with µ = 50 and σ = 18, and the mean is calculated for each sample, then the Expected Value of M is and the Standard Error of M is ?

Expected Value of M is 50 and the Standard Error of M is 3

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation, also called standard error .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

µ = 50 and σ = 18

For the sample

Mean 50 and standard error .

The answer is:

Expected Value of M is 50 and the Standard Error of M is 3

answer: 38.47 is your answer
