Three sets of five mice were randomly selected to be placed in a standard maze but with different color doors. The response is the time required to complete the maze as seen in Table 6.28.
(a) Perform the appropriate analysis to test whether there is an effect due to door color.
(b) Assuming that there is no additional information on the purpose of the experiment, should specific hypotheses be tested by a multiple range test (Duncan's) or orthogonal contrasts? Perform the indicated analysis.
(c) Suppose now that someone told you that the purpose of the experiment was to see whether the color green had some special effect. Does this revelation affect your answer in part (b)? If so, redo the analysis.
