Simulated radiographs with "spots" of various sizes and densities have been imaged and analyzed using two different imaging systems. Each section of the images is "diagnosed" with both systems and declared as missing (NA), detectable at low resolution and confidence or detectable with high resolution and confidence. To simplify the analysis here, the lo and hi are combined to yield the following table:

A. Are the 2 imaging systems independent?
B. Is the "gdens" imaging system more sensitive to the "spots"?
