# Question

Decide in each case whether the hypothesis is simple or composite:

(a) The hypothesis that a random variable has a Poisson distribution with λ = 1.25;

(b) The hypothesis that a random variable has a Poisson distribution with λ > 1.25;

(c) The hypothesis that a random variable has a normal distribution with the mean µ = 100;

(d) The hypothesis that a random variable has a negative binomial distribution with k = 3 and θ < 0.60.
