A sample counted for 10 minutes resulted in 1,000 counts. The background count was 250 counts over a 10 minute period. Assuming negligible radioactive decay of the sample during counting, the net counting rate in counts per minute and the standard deviation are approximately: a. 750±35 cpm b. 75±10 cpm c. 75±3.5 cpm d. 85+5.5 cpm e. 816 cpm
