**a)** Compute the preliminary statistics below.

SS_{BG} = ; df_{BG}
=

SS_{WG} = ; df_{WG}
=

SS_{T} = ; df_{T} =

**b)** Compute the appropriate test statistic(s) to
make a decision about *H*_{0}.

critical value = ; test statistic =

Decision:

**c)** Compute the corresponding effect size(s) and
indicate magnitude(s).

η^{2} = ; is the effect trivial,
small, medium, large

**d)** Make an interpretation based on the
results.

At least one mean is different from another.None of the means differed from one another.

**e)** Conduct Tukey's Post Hoc Test for the following
comparisons:

2 vs. 3: difference = ; significant:

2 vs. 4: difference = ; significant:

**f)** Conduct Scheffe's Post Hoc Test for the
following comparisons:

2 vs. 3: test statistic = ;
significant:

2 vs. 4: test statistic = ; significant:

Answer #1

A)Statistics

SSBG =1054.393 ; dfBG = 3

SSWG = 1465.714;dfWG = 24

SST =2520.107 ;dfT=27

B)Critical value : F_{(3,24,.05)}= 3.0088

Test Statistic : F= 5.755

Decision : Reject H_{0}

C)Effect size

= 1054.393 / 2520.107 = .4184

Magnitude : Medium effect

D)The interpretation is atleast one of the mean is different from.the others

E)Tukey test

2 vs 3 , difference = 7.2857; significance :Not significant

2 vs 4 , difference = .8571; significance :Not significant

F)Scheffe Test

2 vs 3, difference = 7.2857; significance : Not Significant

2 vs 4 difference = .8571; significance :not significant

Please solve this question step by step.
You can online software like SPSS, but show steps for each
part.
If you can't provide step by step answer. Don't bother
to answer at all. I should be able to replicate the
result.

A sample of soy bean plots were divided into three equal groups
in a completely randomized design, and each group received a
different formulation of a selective weed killer (wk). The
researchers measured the area of crop damage inflicted by each
formulation. The aim is to choose the weed killer formulation that
inflicts the least amount of crop damage. What can the researchers
conclude with an α of 0.01?
