Question

A​ two-factor factorial design has 2 degrees of freedom for factor A​ variation, 5 degrees of freedom for factor B​ variation, 10 degrees of freedom for interaction​ variation, 54 degrees of freedom for random​ variation, and 71 degrees of freedom for total variation. Suppose also that SSA=70, SSB=50, SSAB=100, SSE=270, SST=490, MSA=35, MSB=10, MSAB=10, and MSE=5.

Form the ANOVA summary table and fill in all values in the body of the table

The summary of a randomized block experiment with four groups and eight blocks is given below in the following ANOVA summary table. Complete parts (a) and (b).

a. At the 0.05 level of significance, is there evidence of a difference among the four group means? Determine the null and alternative hypotheses. Let c represent the number of groups and r represent the number of blocks.
Ho: H1 = H2 =... = Hc
H1: Not all u are equal (where j= 1, 2, .., c)
Determine the test statistic.
FSTAT = 5.4444 (Type an integer or a decimal.)
Calculate the p-value.

Expert Solution
Step 1

The ANOVA table is GIven, all SS and degrees of freedom are given

we have to check 

1) To test :

a)

H0: Whether the four means are significantly different,

that is 

versusHo:μ1=μ2=μ3=.....μc

H1:the four means are not significantly different,

that is

H1:not all μ's are equal
