Use SPSS for this Application Exercise: (Based off ch. 9, related samples t-test) As part of a study of wheat maturation, an agronomist selected a sample 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 the wheat head. The agronomist wants to know if there is a moisture content difference between the wheat heads. What can the agronomist conclude with an of 0.05? The moisture content data are below.

central	top
62.7 63.6 60.9 63.1 62.7 63.7 62.5	61.7 63.6 60.2 62.1 61.6 62.8 62.3

a) What is the appropriate test statistic? ---Select--- na, z-test, One-Sample t-test, Independent-Samples t-test, Related-Samples t-test, One-Way ANOVA, Within-Subjects ANOVA, Two-Way ANOVA, Correlation, Slope, Chi-Square GoF, Chi-Square Independence b) Condition 1: ---Select ONE--- top portion, wheat maturation, wheat head, moisture content, central portion Condition 2: ---Select--- top portion, wheat maturation, wheat head, moisture content, central portion c) Input the appropriate value(s) to make a decision about H₀. p-value = _____ ;

Decision: ---Select ONE--- Reject H0, Fail to reject H0 d) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and/or select "na" below. d = _____ ;

Magnitude: ---Select ONE--- na, trivial effect, small effect, medium effect, large effect r² = _____ ;

Magnitude: ---Select ONE--- na, trivial effect, small effect, medium effect, large effect e) Make an interpretation based on the results (CHOOSE ONE): The central portion of the wheat head had significantly more moisture than the top portion.

The central portion of the wheat head had significantly less moisture than the top portion.

There was no significant moisture difference between the central and top portion of the wheat head.
