An article in Computers & Electrical Engineering [€œParallel Simulation of Cellular Neural Networks€ (1996, Vol. 22, pp. 61€“84)] considered the speedup of cellular neural networks (CNN) for a parallel general-purpose computing architecture based on six transputers in different areas. The data follow:

(a) Is there evidence to support the assumption that speedup of CNN is normally distributed? Include a graphical display in your answer.

(b) Construct a 95% two-sided confidence interval on the mean speedup.

(c) Construct a 95% lower confidence bound on the mean speedup.
