Inflation of the balloon in the pulmonary artery (PCWP) will give you the following readings either directly or indirectly: 1. RA 2. LV 3. RV 4. PCWP 5. LA 6. PAP

22. A resolution III fractional factorial design always

To run a 2k factorial design in 8 blocks it is necessary to select 3 factors (or interactions) to form the blocks. As a result, the total number of effects confounded with blocks is:

A 23 factorial experiment with two replicates has been run in a chemical process. The response variable is molecular weight. The engineer has used the following factors with their natural units low and high levels as follows:  A (40, 80), B(100, 130), and C(25, 75).  After conducting the experiment, the engineer computes the quantities shown in the following table (using coded units):   Term Effect Estimate Sum of Squares % Contribution A 4.50 81.00 X B X 144.00 35.47 C 2.00 16.00 3.94 AB 5.00 100.00 24.63 AC 3.00 36.00 8.87 BC 2.50 X 6.16 ABC 1.00 4.00 0.99   Answer the following questions (1 – 5) about this experiment.  Each question is worth 8 points.

An experimenter has run a two-factor factorial with factor A (3 levels) and B (2 levels) both factors are random. There are 2 replicates. A partial ANOVA table is shown below.   Factor Sum of Squares Degrees of Freedom A 25.00 2 B 60.75 1 AB 30.00 2 Error 10.00 6 Total 100.75 11   The estimate of the variance component for the main effect of B is
