A drug company is trying to determine how pressure, temperature, and container size influence product yield for a new drug. In the file named Problem14data.xlsx, you are given the yield on several batches of the new drug, as well as the pressure, temperature, and product yield for each batch. Determine an equation that explains how these factors affect yield. If the process is run with high pressure, low temperature, and a large container, you are 95 percent sure the yield of the process will be between _______ and _______. You may ignore nonlinearities and interactions.
