An experiment on a resistor mounted on a ceramic plate in which the impact of four geometrical shapes of the resistors on the current noise of the resistor is studied. Only three resistors can be mounted on one plate. The design and data for the resistor experiment are given as follows:
Shape
Plate 1 2 3 4
1 1.11 0.95 0.82
2 1.70 1.22 0.97
3 1.60 1.11 1.52
4 1.22 1.54 1.18
(a) According to the statement, what is the major factor that we are interested in? What is the blocking factor? How many treatments and blocks in the experiment?
(b) What is the design?
(c) Write the effect model.
(d) How many treatments in a block?
(e) How many times does each treatment appear in the experiment?
(f) In the experiment, what is the number of times that each pair of treatments appears?
(g) Analyze the data from the table. Please provide the ANOVA table and make conclusion.
