The response time in milliseconds was determined for three different types of circuits in an electronic calculator. The results are recorded here.

(a) Using a = 0.01, test the hypothesis that the three circuit types have the same response time.
(b) Analyze the residuals from this experiment.
(c) Find a 95% confidence interval on the response time for circuit three.
