You are deciding to use a diagnostic test for detecting ankle sprains. You have been provided with the following measurement properties: Which test with a positive result would lead to the largest change from the pretest probability? Eagles test +LR = 2 -LR = 0.16 76ers test +LR = 1.3 -LR = 0.51 Phillies test +LR = 7.8 -LR = 0.23 Flyers test +LR = 3.4 -LR = 0.98 a) Eagles Test b) 76ers Test c) Phillies Test d) Flyers Test

Step 1
This means we are looking for the test with the highest positive likelihood ratio (+LR), because a higher +LR indicates a greater increase in the probability of disease after a positive test result. Show more…

A new screening test for Lyme disease has been developed for use in the general population. The sensitivity and specificity of the new test are 60% and 70%, respectively. Three hundred people are screened at a clinic during the first year the new test is implemented. (Assume the true prevalence of Lyme disease among clinic attendees is 10%.) Calculate the following values: The predictive value of a positive test is: A. 33.0% B. 18.2% C. 94.0% D. 22.2% E. 6.0%

The manager of High Point Sofa and Chair, a large furniture manufacturer located in North Carolina, is studying the job performance ratings of a sample of 15 electrical repairmen employed by the company. An aptitude test is required by the human resources department to become an electrical repairman. The manager was able to get the score for each repairman in the sample. In addition, he determined which of the repairmen were union members (code = 1) and which were not (code = 0). The sample information is reported below. Worker Job Performance Score Aptitude Test Score Union Membership Abbott 58 5 0 Anderson 53 4 0 Bender 33 10 0 Bush 97 10 0 Center 36 2 0 Coombs 83 7 0 Eckstine 67 6 0 Gloss 84 9 0 Herd 98 9 1 Householder 45 2 1 Iori 97 8 1 Lindstrom 90 6 1 Mason 96 7 1 Pierse 66 3 1 Rohde 82 6 1 c-1. To test the significance of union membership on job performance, H0: β2 = 0, state the decision rule using a 0.05 level of significance. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.)
