Question 2 A car engineer aims to conduct the experiment to investigate the impacts of several battery factors in an electrical vehicle on the traveling distance (denoted by Y) with a full charge. The engineer wants to reduce the amount of experiment cost for this experiment through the fractional factorial design. The factors of interest are operating temperature (A). battery capacity (B). the battery material (C) and battery density (D) and the data are shown below in Table Q2.
