IT SHOULD BE DONE IN STATGRAPHICS.http://www.statgraphicsstratus.com/default.aspx

please dont forget the comments and screenshots. thanks

TASK for TODAY:

1. Linear regression
2. File -> Open Sample Dataset
3. There is a bunch of data illustrating various statistical problems, yet we are going to stick to linear regression, select theShelf Life Study
4. As soon as selected, data is moved to the active data file. GoHome
5. Statlets -> Regression analysis -> Curve Fitting
6. Select Y data and X data (chlorine and weeks respectively)
7. Comment the results (RMSE, R squared, P-value, regression lines)
8. Click on Opt. X to get the optimized fit not necessary linear
9. Go back and repeat clicking Opt. Y instead.
10. While choosing a curve to fit the data best, what would you look at?

Binomial and Gauss distribution

1. Plot -> Probability distributions -> General distributions
2. Select aBinomial distribution.
3. The theory says a Binomial distribution approaches a Gauss distribution if the np is larger than 5. We're going to visualize Binomial distributions for np value to be 1, 5, and 10.
4. Please choose n and p on your own but to match np given above. (For instance, n=50 and p=0.04 determines np to be 4).
5. Move to theoutput tab. Comment the plots.
6. Make sureResults to savetab has all the three generated samples ready to be saved.
7. GoHome, thenDescribe -> Numeric data -> Distribution fitting
8. Select the first generated sample. In the tabAnalysis Options, selectBinomialandNormalat the same time. Go to theOutputtab. Comment the results.
9. Repeat point g for two other generated samples.
