A 2^K factorial experiment on three factors (A,B,C) were performed and the data table below lists the experimental responses for each of the eight trials. A+ A- B+ 325 346 371 365 330 315 B- C+ 290 302 318 215 222 238 B+ 356 346 321 342 330 318 B- 293 302 315 206 222 238 Determine which of the three factors and their interactions shows significant contribution to the differences found in the response at 5% level of significance. Provide the Half-normal plots and Pareto Chart on standardized effects, as well as the main effects and interaction plots, with a summary statement under EACH chart.
