1. Three different washing solutions are being compared to study their effectiveness in retarding bacteria gmwth in ve-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 randomized block design. Observations are taken for four days, and the data are shown here. Analyze the data from this experiment (use d = 0.05) and draw conclusions. D32 Solution 1 2 3 4 1 13 22 18 39 2 16 24 17 44 3 S 4 1 22
