#8. Using Minitab to illustrate the Central Limit Theorem (CLT), the CLT tells us about the sampling distribution of the sample mean. With Minitab we can easily "sample" from a population with known properties (4,0 , shape). a. Our population consists of integer values X from 1 through 8, all equally likely Р(x) 3D 1/8; х %3D 1, 2, 3, 4, 5, 6, 7, 8 Using methods from the beginning of Chapter 4 in the textbook, find u. Use your calculator to find u. What is the shape of this probability distribution? Does it o =2.29 "look" Normal? b. Take a sample of size 3 from this population and compute the sample mean. Repeat this process 1000 times. Click on Calc > Random Data Rows 1000 Store in columns C1-C3 Distribution Integer Minimum 1 Maximum 8 Compute the mean of each sample (row) and store the sample means in C4.
