Problem 2 Three different washing solutions are being compared to study their effectiveness in retarding bacteria growth in 5-gallon milk containers. The analysis is done in a laboratory, and only three trials can be run on any day. Because days could represent a potential source of variability, the experimenter decides to use a RCBD. Observations are taken for four days, and the data are shown in the table below. Analyze the data from this experiment (use 5% level of significance). Days Solution 1 2 3 4 1 13 22 18 39 16 24 17 44 3 5 4 1 22 a. Is there evidence of a difference in the effectiveness in retarding bacteria growth among the three different washing solutions at the 5% level of significance? Perform ANOVA (from hypotheses to conclusion. b. Has blocking been beneficial at the 5% level of significance? c. Check for the homogeneity of variance assumption. d. If necessary, perform Tukey's test. Show your solution from hypotheses to conclusion. Write the summary table showing the mean per treatment and the appropriate superscripts.
