Dear All: 

  



I need a quick help in R. How I can plot plot the distribution of the T test 
statistic under Ho and Ha with shading areas. Plot overlapping two T distributions and shading overlapping areas under both curves. You choose any values just
 for example. I could not upload any graph for example.

  



Once I know how to create this one, I think I will be able to create the one for normal case.



Thank you very much and sorry for bothering.



Ali
