1.1 A company compares two temperature instruments daily: one coupled to a processor computer and the other used for visual control. Day-to-day variation is expected. On each of three days, the two instruments are used to measure the temperature. Ideally, these two instruments should agree. How many factors are there in this experiment? What are they? List the levels for each factor.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
