Response 29.6 35.2 47.3 NNNNPART 42. 1 12.9 17.6 28.4 22.74. The following two-wayr table gives data for a 2 x 2 factorial experiment with two observations per factor-level combination: The data are saved in the LhLTXT le. Factor E Level 1 2 Factor A i 29.6, 35.1 413, 42.! 2 12.9, 116 23.4, 22."! 9 Identify the treatrnents for this experiment. Calculate and plot the treatment means, using the response variable as v-axis and the levels of factor B as the x-axis. Use the levels of factor A as plotting symbols. Do the treatorent means appear to differ? Do the factors appear to interact\"? [3] Construct an ANDVA table for this EXpa'iment. [3] Test to determine whether the treatment means differ at the o:=.[2|5 levei of signicant. Does the test support your visual interpretation from part a? [3] Does the result of the test in part r: warrant a isst for interaction henveen the two factors? If so, perform it, using o=.'l}5. [3] Do the results of previoUs tests warrant tests of the two factor mean effects? Ifso, perform them, using o=.5. [3]
