I think the value of std deviation (sigma) should be 1 instead of 0.1 in the formulas above. The X_k's are Poisson with mean and variance 1 (sigma = 1). When applying the Central Limit Theorem, the new variance std deviation is (sigma / sqrt(N)) = (1 / 10). In the equation above we divide twice by 10. Once when we used 0.1 instead of 1, and then a second time by multiplying by sqrt(N) in the numerator.

In the equation
I think$\sigma$ should be 1 instead of $0.1$ .
When applying the Central Limit Theorem, we should use the std deviation of the Poisson which is 1.
