Latex allergy in health care workers. Refer to the Current Allergy & Clinical Immunology (Mar. 2004) study of health care workers who use latex gloves, presented in Exercise 7.15 (p. 352). In addition to the 46 hospital LO6 employees who were diagnosed with a latex allergy on the basis of a skin-prick test, another 37 health care workers were diagnosed with the allergy by means of a latex-specific serum test. Of these 83 workers with a confirmed latex allergy, only 36 suspected that they had the allergy when they were asked about it on a questionnaire.
Make a statement about the likelihood that a health care worker with a latex allergy suspects that he or she actually has the allergy. Attach a measure of reliability to your inference.
