An article in Computers & Electrical Engineer$-$ ing $[$Parallel Simulation of Cellular Neural Networks $(1996,$ Vol. $22,$ pp$.6184)]$ considered the speedup of cellular neu$-$ ral networks $($CNNs$)$ for a parallel general$-$purpose computing architecture based on six transputers in different areas. The data follow:$3\mathrm{.}7753023\mathrm{.}3506794\mathrm{.}2179814\mathrm{.}0303244\mathrm{.}6396924\mathrm{.}1396654\mathrm{.}3955754\mathrm{.}8242574\mathrm{.}2681194\mathrm{.}5841934\mathrm{.}9300274\mathrm{.}3159734\mathrm{.}600101$a$.$ Isthereevidencetosupporttheassumptionthatspeedup of CNN is normally distributed?
