Paint used to paint 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 based on a sample of 13 observations gave t = 3.0.
what conclusion is appropriate at each of the following significance levels?
(a) α = 0.05 reject h0 fail to reject h0
(b) α = 0.01 reject h0 fail to reject h0
(c) α = 0.001 reject h0 fail to reject h0
