23	56	72
15	65	29
82		16
56		16
24

Shall we reject or not reject the claim that there is no difference in population mean Mimbres classic black-on-white sherd

A.  Find SS_TOT, SS_BET, and SS_W and check that SS_TOT = SS_BET + SS_W. (Round your answers to three decimal places.)

SSTOT	=
SSBET	=
SSW	=

B.Find d.f._BET, d.f._W, MS_BET, and MS_W. (Round your answers for MS_BET, and MS_W to two decimal places.)

d.f.BET	=
d.f.W	=
MSBET	=
MSW	=

C.

(f) Make a summary table for your ANOVA test. (Round your answers for SS to three decimal places, your MS and FRatio to two decimal places, and your P-value to four decimal places.)
