WebbA type I error occurs when you reject a null hypothesis that is actually true. The probability of a type I error is the alpha level of your hypothesis test. WebbOtherwise, what you say is perfectly ok, you proceed for the calculation of Type II exactly as when you have normal distribution. Now, perhaps your book does not want to confuse you, or wants to introduce the power curve, or is too introductory and prefers to say that this is computationally too hard.

In your case, this means that X is Poisson distributed with λ = 4, and you find that X ≤ 1; i.e. Pr [ X ≤ 1 ∣ λ = 4] = Pr [ X = 0 ∣ λ = 4] + Pr [ X = 1 ∣ λ = 4] = e − 4 4 0 0! + e − 4 4 1 1!.
