Using Minitab for windows for problem 7.15:
1. Generating the random samples:
Calc -> random data -> (specify distribution, uniform, normal or exponential)
generate 500 raws of data (500 the number of random samples)
store in columns C1-C100 (sample size n=100)
Specify the parameters of the distribution
2. Calculate the statistic:
Calc -> Row statistics
Specify statistic of interest (standard deviation for the problem)
input variables C1-C100
store result in C101
use Calc -> Calculator to get the sample variance and store result in
column C102
Finally, C102 contains 500 realizations from the sampling distribution of the sample variance. Obtain a histogram (Graph -> Histogram) and numerical measures (Stat -> basic statistics -> display descriptive statistics) to summarize this sampling distribution.
Discuss and compare the results for the three distributions.
