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? (round your p-values to three decimal ) n = 16, t = 3.3, a = 0.05p-value =(b) n = 8, t = 1.8, a = 0.01p-value =(c) n = 26,t = -0.6p-value =
