Answer:
(a) P-value = 0.001
Conclusion: The average reflectometer reading for the new type of paint under consideration is greater than 20.
(b) P-value = 0.036
Conclusion: The average reflectometer reading for the new paint under consideration is 20
Step-by-step explanation:
The test is a one-tailed test because the alternate hypothesis is expressed using greater than.
(a) n = 16, t = 3.3, a = 0.05
Cumulative area of the test statistic t is 0.9995
P-value = 1 - 0.9995 = 0.0005 = 0.001 (to 3 decimal place)
Conclusion:
Reject H0 because the P-value 0.001 is less than the significance level 0.05.
(b) n = 8, t = 1.8, a = 0.01
Cumulative area of the test statistic t is 0.9641
P-value = 1 - 0.9641 = 0.0359 = 0.036 (to 3 decimal places)
Conclusion:
Fail to reject H0 because the P-value 0.036 is greater than the significance level 0.01
Alex should use Easyvans because if he gets a car they will charge more money per season so he would get charged 172 per season so if he got the other one you dont have to pay you just pay once.

plug in (-1) for x, this gives you (-2)(-1)+3 which is (2)+3 =5
