suppose we have a population {2,6,10}. write the sampling distribution of the mean for simple random samples of size N=2? what is the mean of this distribution what is the standard deviation?

Homework Answers

Answer #1

Answer:-

Given that:-

We need to choose sample of 2 and contruct the sample distribution of the mean for example of 3 number we can choose

2,6 mean

2,10 mean

6,10 mean

that are the only 3 combination with 2 sample size mean of this distribution is

mean of this distribution is 6

Standard Deviation,
