Problem S.1 Can organic methods be used successfully to control harmful insects and limit their effect on sweet corn? Five treatment groups were considered: (1) Nematodes, (2) Wasps, (3) Nematodes + Wasps, (4) Bacteria, (5) Control After treatment, ears of corn from each group will be weighed (in ounces). The following table gives the results for an experiment based on these treatment groups. Nem 19.5 16.0 12.5 13.0 ) 13.5 10.0 17.0 7.5 9.0 15.5 8.0 11.5 Bact 20.0 18.5 19.0 13.0 14.5 18.0 17.0 13.0 14.0 13.0 10.5 13.0 Wasps 13.5 17.5 11.5 11.5 14.0 13.5 11.5 12.5 11.5 10.5 10.5 7.5 Nem + Wasps 8.5 13.0 12.0 10.0 12.5 8.5 9.5 7.0 10.5 10.5 13.0 9.0 Control 9.0 6.5 7.0 6.0 10.0 8.0 7.0 5.5 14.5 13.0 6.0 7.0 This problem requires the use of Minitab. Minitab instructions are listed on the next page. 1. Use Minitab to create a side-by-side boxplot for the 5 treatments. Print the graph on include some remarks on the strength of evidence against the usual ANOVA null hypothesis. 2. Use Minitab to construct the ANOVA table and test the null hypothesis at the a = 0.05 level. Your Minitab output should something like the following ('?' included intentionally so that I don't give everything away). Note that the format of the output slightly differs depending on version of Minitab you are using. But all the numbers should be the same. Minitab Ver. 16 Minitab Ver. 17 Source DF SS MS Source DF Adj 85 Adj MS F-Value P-Value Factor 4 ???.?? ?7.?? 10.01 0.000 Factor 4 ??7.?? ??.?? 10.01 0.000 Error 65 777.?7 7.?7 Error 65 797.77 7. ?7 Total 59 ??7.?? Total 59 ??7.?? Minitab Ver. 16 Minitab Ver. 17 3. Also, use the Tukey Multiple Comparisons method in Minitab to compare the various treatment means. Be sure to comment on the various treatment mean comparisons that Minitab provides in the output. 4. Based on what you found from the Tukey comparisons, use the underlining technique as discussed in class to illustrate the relationship between the different means
