Question

please show all work it's more important that I understand howyour arrived at the solution, I need to make sure I know what I amdoing. . Thank you a) State the null and alternate hypothesis. Will we usaa left, right or two-tailed test? what is the lefverl ofsignificance?
b) identify the sampling distribution to be used: standard normalor the Student's t. Compute the z or t value of the sampletest statistic and sketch its location. c) Find the P value for the sample test statistic. d) Should we reject or fail to reject the nullhypothesis? A new bus route has been established between downtownDenver and Englewood, a suburb of Denver. Dan has taken thebus to work for many years. For the old bus route, he knowsthat the mean waiting time between buses at his stop was 18.3minutes. however, a random sample of 5 waiting times between busesusing the new route had a mean of 15.1 minutes with s = 6.2minutes. Does this indicate that the population mean waitingtime for the new route is different from what it used to be? use = .05. please show all work it's more important that I understand howyour arrived at the solution, I need to make sure I know what I amdoing. .

Explanation / Answer

Yes this is two tailed test because thepopulation mean waiting time for the new route is different from whatit used to be. Since for the word different we use .Therefore it is a two tailed
