A single replicate 24 experiment is designed. The
experiment has factors A, B, C, and D, each of which can be set to
+1 or -1. We conduct a single replicate of this experiment,
collecting the response for each possible combination of factor
settings. This data is in the file HW_DOEInterp_180.csv .
We compute the factorial and interaction effects from this data,
and determine that the following effects are significant:
Factorial Effect B = -15.265
Factorial Effect C = -11.433...

Four factors influence the taste of pizza: crust (A),
toppings (B), temperature (C), and sauce
(D). Each can be run at two levels, producing a
24 design. At each run in the design, samples of pizza
are given to a test panel consisting of 20 people. Each tester
assigns a point score from 1 to 10 to the pizza. Total score is the
response variable, and the objective is to find a formulation that
maximizes the total score. Two replicates...

2. An experiment was run in a semiconductor fabrication plant in an effort to increase yield. Five factors, each at two levels, were studied. The factors (and levels) were A aperture setting (small, large), B-exposure time (20% below nominal, 20% above nominal), C-development time (30s, 45s), D mask dimension (small, large), and E: etch time (145min, 15.5min). The unreplicated 25 design shown below was run. b 34 bd 32 be 35 bde 30 ab 55 abd 50 abe 52 abde...

4. In a process development study on yield, four factors were studied, each at two levels: time (A), concentration (B), pressure (C) and temperature (D). A single replicate of a 24 design was run, and the resulting are shown in the Table below a. Construct a normal probability plot of the effect estimates. Which factors appear to have large effects? b. Conduct an analysis of variance using the normal probability plot in part (a) for guidance in forming an error...
