An experimenter has run a two-factor factorial with factor A (3 levels) and B (2 levels) both 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

What organ system protects underlying tissue, and helps regulate body temperature

Which part of the inner ear is responsible for sound conduction?

What organ system collects and cleanses interstitial fluid, and returns it to the blood; provides immunity

Which of the following intercellular proteins is essential for exocytosis to release products into the extracellular fluid?

Sound and light both travel in waves.

Which of the following is not an ear ossicle?

An infant is lying in a crib watching and listening to a colorful mobile. Which of the following statements is correct concerning a mobile for an infant?

An experimenter is studying the performance of 3 machines. Each machine has two heads that produce the output product. She runs a two-stage nested design in which output from all three machines, both heads on each machine, and 4 observations on each machine-head combination are collected. However, the only computer program she has will only analyze factorial designs, so she (incorrectly) analyzes her experiment as a 2-factor factorial with 4 replicates and obtains the following results:   Factor Sum of Squares Degrees of Freedom Machines 50.00 2 Heads 45.00 1 Machine-head interaction 20.00 2 Error 10.00 18 Total 115.00 23   What is the correct sum of squares for the heads-within-machines nested effect?

A 23 factorial experiment with only two replicates (16 runs) has been run in a chemical process. The response variable is molecular weight. The engineer has used the following factors with their natural low and high levels as shown:  A (40, 80), B(100, 130), and C(25, 75).  After conducting the experiment, the engineer computes the quantities in the following table (using coded units):   Term Effect Estimate Sum of Squares % Contribution A 4.50 81.00 19.95 B 6.00 144.00 X C X 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. Please select the correct answer.
