(a)
Interpretation:
The absolute and the relative uncertainty is to be determined for the measurement involving 600 count at 90% confidence level.
Concept introduction:
The standard deviation can be calculated as follows:
Also, the relative standard deviation can be calculated as follows:
The absolute uncertainty =
The relative uncertainty =
The formula for the confidence of counting intervals is −
