Another type of painted ceramic vessel is called
three-circle red-on-white
(
Mimbres Mogollon Archaeology). At four different sites in the Wind Mountain archaeological region, the number of such sherds was counted in local dwelling excavations.

Site I	Site II	Site III	Site IV
15	13	38	15
22	2	20	21
4	31	15	13
15	7	44	34
17	23		12
	11		12

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? Use a 5% level of significance.

(a) What is the level of significance?

(b) Find
SS_TOT, SS_BET
, and
SS_W

and check that
SS_TOT
= SS_BET
+ SS_W
. (Use 3 decimal places.)

SS_TOT	=
SS_BET	=
SS_W	=

Find
d.f._BET, d.f._W, MS_BET
, and
MS_W
. (Use 3 decimal places for
MS_BET
, and
MS_W
.)

df_BET	=
df_W	=
MS_BET	=
MS_W	=

Find the value of the sample
F
statistic. (Use 3 decimal places.)

What are the degrees of freedom?
?(numerator)
?(denominator)

(c) Find the
P-value of the sample test statistic. (Use 4 decimal places.)

(f) Make a summary table for your ANOVA test.
