So I got this data (from a real annoying software package which doesnt give me all the data-points as an export) where I only get means and SDs....so not all the data which produces these means and SDs.

How can do pairwise comparisons with just the given means and SDs?

This is my table:

df <- tibble(Setup = c(2,2,2,2,2,3,3,3,3,3,4,4,4,4,4),
         Sphere = c(1,2,3,4,5,1,2,3,4,5,1,2,3,4,5),
         Mean = c(5,6,9,8,7,3,2,4,5,6,25,32,12,45,14),
         SD = c(1,3,4,2,1,3,4,2,1,3,11,15,2,23,25))

Where Setup=2 is the reference group
