O Reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20.
O Reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20.
O Do not reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20.
O Do not reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than
20.

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 H: = 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.)
A USE SALT
(a) n = 11, t = 3.3, a = 0.05
P-value = 0.0040
