A single observation of a random variable (that is, a sample of size n = 1) having a geometric distribution is used to test the null hypothesis θ = θ0 against the alternative hypothesis θ = θ1 for θ1 < θ0. The null hypothesis is rejected if the observed value of the random variable is greater than or equal to some positive integer k. Find expressions for the probabilities of type I and type II errors.
