The paint used to make lines on roads must reflect enough light to be clearly visible at night. Let μ denote the true average reflectometer reading for a new type of paint under consideration. A test of versus H₀ : μ = 20 will H: μ > 20 be based on a random sample of size n from a normal population distribution. What conclusion is appropriate in each of the following situations?
