Submit Answer 5. [-17 Points] DETAILS DEVORESTAT9 8.3.031.MI.S. MY NOTES PRACTICE ANOTHER 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 Mo! u = 20 versus M, > 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 placer.) 1 USE SALT (a) n = 11,t=31,-0.05 P-value = State the conclusion in the problem context Reject the null trypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. Do not reject the ruil hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. O Reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20 Do not reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20 (b) n = ),t = 1.7,-0.01 P value = State the conclusion in the problem context. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. Reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. Do not reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. O Reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. a (c) n = 28, -04 p.value State the conclusion in the problem context. Do not reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. Do not reject the nult hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20 Reject the null hypothesis. There is sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20. Reject the null hypothesis. There is not sufficient evidence to conclude that the new paint has a reflectometer reading higher than 20 You may need to use the appropriate table in the Appendix of Tables to answer this question.
