A homework question for an SAS output of an animal experiment

Student looking for help on any of the questions below as I really can't grasp it. Anything from answers to a guide of which formulas to use would be appreciated. Thank you.

We're happy to help with specific questions about homework assignments. We need to see you make some effort on this first. Show us the code you used; show us your current answer to the questions stated, ask specific questions. But we are not happy to simply answer questions that amount to us doing your homework with you making no effort whatsoever.

So far I have worked out that the f table value for the treatment is 3.863 for both for both block and treatment both have treatment df and error df of 3,9. With block critical F value at 17.09 and treatment at 5.24. I understand that superscripts are used to show treatments significantly different from each other depending on P value signified by a letter. I do not know however what indicates the difference amounts.

Show your code, so we can see from where to proceed. And provide some usable example data (which you can take straight from your homework assignment).

Hello!

I entirely agree with @PaigeMiller and @Kurt_Bremser , but in this case one has to admit, that the questions at hand are not primarily a coding questions. So I guess one does not need to be that "strict".

To help starting the discussion: @humungus surely you have used a data step to build the data table. Could you post that here, just to spare people this work ... 🙂 Then you surely have used sas to come up with the calculation of standard errors ... could you show that as well ... just to help people in helping you.

Kind Regards
