Section I: Multiple Choice Select the best answer for each question. Questions T3.5 and T3.6 refer to the following setting. Scientists examined the activity level of 7 fish at different temperatures. Fish activity was rated on a scale of 0 (no activity) to 100 (maximal activity). The temperature was measured in degrees Celsius. A computer regression printout and a residual plot are given below. Notice that the horizontal axis on the residual plot is labeled Fitted value.

ANSWER:Step 1 of 2
Using the computer regression printout and the residual plot we have to determine the activity level rating for the fish at a temperature of
