Problem 4 (10 points) : 4.1 An article in the Annals of Nuclear Energy (" Statistical Analysis of the Fort Calhoun Reactor Coolant Pump System," Vol. 24(3), 1997) considered the effect of five factors on a recirculating pump motor power input ( KW) . The factors were temperature settings at the sites: A = Upper guide bearing, B = Upper thrust bearing, C = Lower thrust bearing, D = Lower guide bearing, E = Seal winding . The levels were coded as A: -1 = 140, +1 = 160; 8: -1 = 140, +1 = 160; C: -1 = 140, +1 = 160; D: -1 = 140, +1 = 160; E -1 = 140, +1 = 160. Estimate the factor effects. What is the effect for D? What is the effect for B*C? What is the effect for A*B*C*D? Enter your answers to 2 decimal places. 2.5 Points effect D : FRE LATEX ?
