For Questions 6 complete the following: a) State the null and alternate hypotheses. Will we use a left-tailed, right-tailed, or two-tailed test? What is the level of significance? b) Identify the sampling distribution to be used: standard normal or the Student's t. Compute the z or t value of the sample test statistic and sketch its location. c) Find the P value for the sample test statistic. d) Should we reject or fail to reject the null hypothesis? Question 6 A new bus route has been established between downtown Denver and Englewood, a suburb of Denver. Dan has taken thc bus to work for many years. For the old bus route, he knows that the mean waiting time berween buses at his stop was 18.3 minutes. However, a random sample of 5 waiting umes between buses using the new route had a mean of 15.1 minutes with s 6.2 minutes. Does this indicate that the population mean waiting time for the new route is different from what it used to be? Use a 05.

Coordinate Geometry

Coordinate geometry, also known as analytic geometry or Cartesian geometry in classical mathematics, is a type of geometry that is studied using a coordinate system. Coordinate geometry is a branch of mathematics that describes the position of points on a plane using an ordered pair of numbers called coordinates.
