Time and temperature are key properties in many chemical curing processes. Process engineers are often concerned with determining a "bake window" for a product, that is, finding a time/temperature combination that achieves the best results in the smallest amount of time. In one process the engineers studied three temperature levels on their oven at two different time intervals and measured the yield of parts (if the parts were not cured correctly they could not be used). Using the data set cure . txt summarize the data that the engineers collected, and based on the data make a recommendation for the best time/temperature combination.
