Refer to Example 11.1 and the reaction data presented in Table 11.1. Consider the straight-line model E1y2 = b0 + b1x, where y = reaction time (in seconds) and x = percent of drug received.

a. Use the method of least squares to estimate the values of b0 and b1.

b. Predict the reaction time when x = 2%. LO9

c. Find the SSE for the analysis.

d. Give practical interpretations of b n 0 and b n 1.
