Question

An experiment has a single factor with three groups and five values in each group. In determining the among-group variation, there are 2 degrees of freedom. In determining the within-group variation, there are 12 degrees of freedom. In determining the total variation, there are 14 degrees of freedom. Also, note that SSA 36, SSW 108, SST 144, MSA = 18, MSW 9, and FSTAT = 2. Complete parts (a) through (d). Click here to view page 1 of the F table. Click here to view page 2 of the F table. Click here to view page 3 of the F table Click here to view page 4 of the F table a. Construct the ANOVA summary table and fill in all values the table. Mean Square Degrees of Sum of (Variance) Source Freedom Squares Among 2 groups 12 Within groups 14 (Simplify your answers.) Total b. At the 0.05 level of significance, what is the upper-tail critical value from the F distribution? Fo.05 (Round to two decimal places as needed.)

Answer 1

Source	df	SS	MS	F
among	2	36	18	2.00
within	12	108	9
total	14	144

b)

upper tail critical value F_0.05 = 3.89

c)

reject Ho if test statistic Fstat >=3.89

d)

since Fstat is smaller than the ...fail to reject ho ,there is not sufficient evidence to conclude......
