With reference to Exercise 13.9, use Table II on page 492 to find values corresponding to k0.025 and k'0.025 to test the null hypothesis λ = 3.6 against the alternative hypothesis λ ≠ 3.6 on the basis of five observations. Use the 0.05 level of significance.
In exercise
Modify the critical regions on pages 365 and 366 so that they can be used to test the null hypothesis λ = λ0 against the alternative hypotheses λ > λ0, λ < λ0, and λ ≠ λ0 on the basis of n observations. Here λ is the parameter of the Poisson distribution.
