Generate 100 samples of size n=8 from an exponential distribution with mean 3 . Each row of your data will denote an observed random sample of size 8, from an exponential distribution with mean 3. Obtain sample mean for each sample, store in another column and make a histogram for sample means. Repeat for n=100. Compare and interpret the histograms you obtained for n=8 and n=100. Submit the histograms along with your one small paragraph comparison.

Can you solve it using minitab and explain the steps (especilly how to find samples) ? Thank you in advance.

Expert Solution

Go Calc Random Data Exponential then enter followings:

Go Row Statistics and enter following as follows:

Go Graph Histogram Slect "Simple" Click OK Select C9 Enter OK.

From above histogram, we see that the distribution of sample mean is positively skewed.

Now repeat the process with sample size n=100 then

From above histogram we see that the distribution of sample mean is symmetric and belled shaped.
