Consider the regression model fit to the gray range modulation data in Exercise 12-19. Use the useful
Question:
(a) Test for significance of regression using α = 0.05. What is the P-value for this test?
(b) Construct a t-test on each regression coefficient. What conclusions can you draw about the variables in this model? Use α = 0.05.
Exercise 12-19
An article in Optical Engineering [Operating Curve Extraction of a Correlators Filter (2004, Vol. 43, pp. 27752779)] reported on the use of an optical correlator to perform an experiment by varying brightness and contrast. The resulting modulation is characterized by the useful range of gray levels. The data follow:
