![The paint used to make lines on roads must reflect enough light to be clearly visible at night. Let u denote the true average reflectometer reading for a new type of paint under consideration. A test of Ho: µ = 20 versus H: 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? (Round your P-values to three decimal places.)
