STAT 8200 — Design of Experiments for Research Workers Homework 1 – Due Thursday, September 2 SHOW ALL WORK 1. A test program was conducted to evaluate how the quality of epoxy glass fiber pipes is affected by the operating conditions (Normal vs. Severe) used during their production. The test program required sixteen pipes, half of which were made at each of two manufacturing plants. Each pipe was produced under one of two operating conditions and the water temperature at which each pipe was tested was measured at the time of the test. The following table summarizes the experimental conditions for this study: Run Plant Operating Water Number Conditions Temp. ( F) 1 1 Normal 175 2 1 Normal 173 3 1 Severe 170 4 2 Severe 176 5 1 Normal 165 6 1 Normal 162 7 2 Normal 167 8 1 Severe 172 9 2 Normal 159 10 2 Severe 164 11 2 Normal 164 12 1 Severe 171 13 2 Severe 160 14 2 Severe 171 15 1 Severe 175 16 2 Normal 165 Identify which of the following statistical design features are included in the test
