Question: Removing water from paper. The percentage of water removed from paper as it passes through a dryer depends on the temperature of the dryer and the speed of the paper passing through it. A laboratory experiment was conducted to investigate the relationship between dryer temperature T at three levels (100°, 120° and 140°F) and exposure time E (which is related to speed) also at three levels (10, 20, and 30 seconds). Four paper specimens were prepared for each of the 3 × 3 = 9 conditions. The data (percentage of water removed) are shown in the accompanying table. Carry out a complete analysis of the data using an available statistical software package.
