Chapter 10 HW, Questions 4 - 7: Calculate the SEM and the Z-test by hand for the given research scenario, and then interpret the results. HINT: It can be helpful to first determine which portions of the scenario are referring to the sample and which are referring to the population so that you know which numbers go in each part of the equations. Research Scenario: In comparing incidents of lice in a small school system, it was found that there were 15 break-outs among the 300 students. How does that compare to the state average which is 16 incidents +15.10? (0 = .05) [1/2 pt. each]
