2. Geothermal power is an important source of energy. Since the amount of energy contained in 1 pound of water is a function of its temperature, you might wonder whether water obtained rom deeper wells contains more energy per pound Location of Well Average (max.)

Ellis, . Following steps A-E in the previous question, do a full regression analysis, using hole depth as the explanatory variable. (4 points) B. Using the regression equation, predict the temperature of the water in a well with an average drill hole depth of 2000m. Is this a reliable prediction? (1 point) 3. Use the potency and temperature data below. An experiment was conducted to observe the effect of an increase in temerature on the potency of an antibiotic. Three 1-ounce portions of the antibiotic were stored for equal lengths of time at each of these temperatures: 30', 50", 70', and 90", The potency readings observed at each temperature of the experimental period are listed here: Potency Readings, y 38, 43, 29 32, 26, 33 19, 27, 23 14, 19, 21 Temperature, x 30 50 70' 90 As before, conduct a full regressional analysis (see 1A-1E) to answer this question: Within the sample data, is a one-degree increase in storage temperature of antibiotics associated with a decrease in potency? If so, how much? In this case, you'll need to determine which is the response variable in your analysis. Looking at the question, which variable would you say the researcher is more interested in predicting? The predicted variable is the response variable. (You can also look at the research question as an interpretation of a regression coefficient-when you write a statement that interprets a regression coefficient, which variable goes first?) (5 points)
