Susan's grades8,8,7,9,7,8,8,6,8,7,8,8,8,7,8,8,10,9,9,9 roughly what is a typical distance from the mean for susan

You can find the mean by adding all the grades up to get 160, and there are 20 grades, so the mean is 160/20 = 8. Just visually "inspecting" the list, it appears typically Susan's grade are about a distance of 1 from the mean... some are exactly 8, so zero distance... some are 9, some are 7, and only one is 6 and only one is 10.
