An experimenter has run a single replicate of a 2^4 design. The following effect estimates have been calculated: A = 76.95 AB = -51.32 ABC = -2.82 B = -67.52 AC = 11.69 ABD = -6.50 C = -7.84 AD = 9.78 ACD = 10.20 D = -18.73 BC = 20.78 BCD = -7.98 BD = 14.74 ABCD = -6.25 CD = 1.27 Construct a normal probability plot of these effects. Identify a tentative model, based on the plot of the effects in part (a).
