As part of a study of wheat maturation, an agronomist selected asample of wheat plants at random from a field plot. For each plant,the agronomist measured the moisture content from two locations:one from the central portion and one from the top portion of thewheat head. The agronomist hypothesizes that the central portion ofthe wheat head has more moisture than the top portion. What can theagronomist conclude with ? = 0.01? The moisture content data arebelow.

a) What is the appropriate test statistic?
---Select--- na, z-test, One-Sample t-test, Independent-Samplest-test, Related-Samples t-test
b)
Condition 1:
---Select--- top portion wheat maturation moisture content wheathead central portion
Condition 2:
---Select--- top portion wheat maturation moisture content wheathead central portion
c) Compute the appropriate test statistic(s) tomake a decision about H0.
critical value = ; test statistic =
Decision: ---Select--- Reject H0, Fail to rejectH0
d) If appropriate, compute the CI. If notappropriate, input "na" for both spaces below. (Please say if"na")
[ , ]
e) Compute the corresponding effect size(s) andindicate magnitude(s).
If not appropriate, input and/or select "na" below.
d = ; ---Select--- na, trivial effect, smalleffect, medium effect, large effect
r2 = ; ---Select--- na, trivialeffect, small effect, medium effect, large effect
f) Make an interpretation based on the results.(select one)
-The central portion of the wheat head had significantly moremoisture than the top portion.
-The central portion of the wheat head had significantly lessmoisture than the top portion.
-There was no significant moisture difference between thecentral and top portion of the wheat head
