Use the following to match each scenario to the type of procedure. Mark the corresponding letter for each question. Each answer can only be used once. A. One sample z test for a mean B. One sample t test C. One proportion z test 53. Match Oregon State University would like to know whether the proportion of students that missed 2 or fewer days of class during the summer term is less than 70%. They take a simple random sample of 1000 students and ask whether the student has missed two or fewer days of class. What type of test should the university use to test their claim of 70%? 54. Match A construction engineer would like to test whether a large batch of pressure treated lumber boards are acceptable for use by a given manufacturer. The boards are advertised as 4"x4"x16' and should weigh 77 lbs. For the boards to be acceptable there should be no evidence that the boards weigh other than 77 lbs on average. The engineer takes a random sample of 30 boards and finds the average of the sample to be 76.8lbsand the standard deviation to be 0.2lbs What type of test is appropriate for this scenario? 55. Match A company would like to advertise that their new fishing line has an average breaking strength greater than 15 kilograms. The lines breaking strength is known to vary in the population on average 2.8 kilograms. To test the breaking strength of their new product the company takes a random sample of 50 lines, the average strength measure is 16.1 kilograms. What type of procedure should they use to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.
