Problem 16E

A mixture of sucrose and water was heated on a hot plate, and the temperature (in °C) was recorded each minute for 20 minutes by the three thermocouples.

a. Compute the least-squares line for estimating the temperature as a function of time, using T1 as the value for temperature.

b. Compute the least-squares line for estimating the temperature as a function of time, using T2 as the value for temperature.

c. Compute the least-squares line for estimating the temperature as a function of time, using T3 as the value for temperature.

d. It is desired to compute a single line to estimate temperature as a function of time. One person suggests averaging the three slope estimates to obtain a single slope estimate and averaging the three intercept estimates to obtain a single intercept estimate. Find the equation of the line that results from this method.

e. Someone else suggests averaging the three temperature measurements at each time to obtain  = (T1 + T2 + T3)/3. Compute the least-squares line using  as the value for temperature.

f. Are the results of parts (d) and (e) different?

Step 1 of 3

GEOL 207 Environmental Geology More Atmosphere Stuff!! - Albedo  reflection of light on earth. o Clouds  - Air and atmosphere in a system o Circular system (atmosphere)  Much faster than other circular systems such as plate tectonics. - CIRCULAR SYSTEMS (air) o Energy comes from the sun o Buoyancy  The ability or tendency to float in water or air or some other fluid.  Factors  Pressure  Volume  Temperature  If factor (variable) is constant, you can omit it from the equation - Lateral Movement o Sideways movement
