10-8. A 2048×2048×12-bit image is compressed at 10 to 1 compression
ratio. How many bits are present in the compressed image?
11-1. Suppose 3600 counts were accumulated for a sample counted for
10 minutes. Background contributed 784 counts over a counting
interval of 6 minutes.
a. Find the estimated standard deviation and the percent estimated
standard deviation of the sample count rate uncorrected
for background.
b. What are the estimated standard deviation and the percent
estimated standard deviation for the background count
rate?
c. What are the estimated standard deviation and the percent estimated
standard deviation of the sample count rate corrected
for background?
