Question

(8 pts) In an experiment design, the maximum value of variable 1' is 20 ma (milli corresponding to 7.2 ma? amps). and the minimum value is 4 ma. What is the dimensionless, scaled value of xi 2. (8 pts) A 4 factor, 2 level design of experiments will be used. How many experiments/trials will be run? 3. (8 pts) In an experiment, a process is modeled as y = ao + axi + ax2 + axx2, and the values in the table at right are found for the coefficients. Which variable, or combination of variables, are the most important to effect an increase in the output y? Explain 20.47 -2.6 4.3 -6.2 ao a2 a3

just need answers. not solutions

Answer 1

1 x = 0.2 2 4 times 2 = 8 3 x_1 is the most important to effect an increase in output y
