A medicine for reducing body temperature is available in 30mg, 60mg, or 90 mg doses. When administered to several men and women, the average drops in temperature were as shown in the interaction plot below. The Y-axis shows the drops in temperature (in Fahrenheit). Based on the interaction plot, which of these two statements is correct? S1: When the dosage is changed, the expected drop in temperature depends on the patient’s gender. S2: There are no interaction effects.

For the following data set, define y_new = Log (y), and x_new = sqrt(-1 + 1/x), where x_new >= 0. Here the Log is to the base 2. Using the method of least squares as we did in class, prepare a linear regression model to predict $y_new as a function of x_new. What is the predicted value of y when x=1/17?
