Environmental engineers need to minimize the time required to compost a municipality's green waste. They create a single replica 2⁴ experiment to test the effect of the following factors on time to finish a batch of compost: (A) moisture level, (B) oxygen level, (C) amount of compost starter added, (D) size of shredded materials. Running this experiment, they obtain the data in ExpDes2.csv
