Chapter 32, Problem 32-7(choose chapter or problem)
For a particular radioactive sample, the total counting rate (sample plus background)was 450 cpm, and this value was obtained over a 15.0-min countingperiod. The background was counted for 2.0 min and gave 7 cpm. Estimate(a) the corrected counting rate Roo(b) the standard deviation associated with the corrected counting rate IT;.(c) the 95% confidence interval associated with the corrected counting r~te.
