1 vs. 4: difference = __________ ; significant: YES OR NO

f. Regardless of the *H*_{0} decision in
**b)**, conduct Scheffe's post hoc test for the
following comparisons:

1 vs. 3: test statistic = ___________ ; significant:
---Select---YesNo

3 vs. 4: test statistic = ____________; significant:

Answer #1

a. Compute the preliminary statistics below.

SS_{BG} = 1,274.964
; df_{BG} = 3

SS_{WG} = 1,207.143
; df_{WG} = 24

SS_{T} = 2,482.107 ;
df_{T} = 27

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

critical value = 4.718 ; test statistic = 8.449

Decision: Reject Ho

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

*η*^{2} = 0.514; -medium effect

d. Make an interpretation based on the results.

-At least one mean is different from another

e. Regardless of the *H*_{0} decision in
**b)**, conduct Tukey's post hoc test for the
following comparisons:

1 vs. 3: difference = 4.571 ; significant: NO

1 vs. 4: difference = 16 ; significant: YES

f. Regardless of the *H*_{0} decision in
**b)**, conduct Scheffe's post hoc test for the
following comparisons:

1 vs. 3: test statistic = 4.571 ; significant: No

3 vs. 4: test statistic = 16; significant: Yes

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?
