Another type of painted ceramic vessel is called three-circle red-on-white ( Mimbres Mogollon Archaeology). At four different sites in an archaeological region, the number of such sherds was counted in local dwelling excavations.
|Site I||Site II||Site III||Site IV|
Shall we reject or not reject the claim that there is no difference in the population mean three-circle red-on-white sherd counts for the four sites?
(b) Find SSTOT, SSBET, and SSW and check that SSTOT = SSBET + SSW. (Use 3 decimal places.)
Find d.f.BET, d.f.W, MSBET, and MSW. (Use 3 decimal places for MSBET, and MSW.)
(c) Find the value of the sample F statistic. (Use 3 decimal places.)
