A farmer wants to grow as much com as he can, so he is interested in what affects his corn
yield? for this lab, we are looking at the yield, in bushels per acre, from 3 different varieties of
corn. Refer to the Minitab Output provided on Moodle; do not pertorm any unnecessary
calculations Which of the following are the correct hypotheses for this test? Select one: a. Ho:
1=2=3=0 Ha: at least one of the s is different from the rest. b. HHo:1=2=3 Ha: at least one of the
i 's is different from the rest. c. Ho: 1=2=3Ha:1=2=3 d. Ho:1=2=3 Ha: 1=2=3 The next few
questions are asking you to check the required assumptions and conditions.
Factor Information Analysis of Variance Model Summary Pooled StDev =7.75688
Residual Plots for Yield Versus Order
Tukey Pairwise Comparisons Grouping Information Using the Tukey Method and 95%
Confidence Tukey Simultaneous Tests for Differences of Means
Is the equal variance assumption met? Does the plot thickeri? condition: since the vs fit plot
shows Similar Variance condition: since the boxplot shows Is the Normal Population assumption
met? Qheck both the Nearly Normal condition and the Outier condition, and refer to the
appropiate graphs. Identify the values of the test statistic-and P-value from the Minitab output.
Would it be appropriate to run multiple comparisen test (i.e. Tukay) to see which corn variety
has the fargest yield? since Now, we want to look a little doser at where there might be a
difference. How many pairwise comparisons do we need to consider? Answer Interpret the first
Tukey confidence interval on the output in the context of the problem. This is the interval
comparing Variely 2 to Variety 1 (calculated as Variety 2 - Variety 1 )
Based on the Tukey confidence intervals, which com varieties differ in their effect on mean com
yield? Variety 1 and Variety 2 Variety 1 and Variety 3 Variety 2 and Variety 3.
