Fizzy Drugs wants to optimize the yield of a chemical process by determining the relationship between yield, container size (between 1.3-1.5 cubic meters), pressure (between 4-4.5 mm), and temperature (between 22-30 degrees Celsius). Scientists collected data on experiments run at the lower and upper levels of these three variables. They are asked to analyze the data to determine the relationships and interactions between the variables and recommend process settings.
