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 h0: μ = 20 versus ha: μ > 20 will be based on a random sample of size n from a normal population distribution. what conclusion is appropriate in each of the following situations?

(a) n = 14, t = 3.1, α = 0.05

(b) n = 10, t = 1.8, α = 0.01
