I think there is some slop in the equations that needs fixing.

I think the second equation:

\(R(n) = \sqrt{\overline{x_i}^2 + \overline{y_i}^2}\)

should be:

\(R_n = \sqrt{\overline{X}^2 + \overline{Y}^2}\)


I think the third equation:

\(\bar X, \bar Y \sim N(0,\sigma^2/n)\)

should be:

\(\bar X, \bar Y \sim N(0,\frac{\sigma}{\sqrt{n}})\)


There is another fine point that should be explicitly stated. The sample of three shots uses n as sample size. But the \(\sigma\) is the population standard deviation, not the sample standard deviation s.
