I was hoping that somebody would check my work. Any input is appreciated.
A decay rate of a radioactive sample is being measured using a Geiger counter. During a 10 second measurement 100 decays are registered.
what is the error associated with the result?
\sigma_{y} = \frac{\sigma}{\sqrt{N}}
My work:
\sigma^2 = np = (100)(1/10) = 10
so \sigma = \sqrt{10}
putting this into the previous equation where I make N=100 I get an error around 0.316. Did I do that right?
