Dr. Rоdriguez wаs аssessing the net sensitivity аnd specificity оf twо versions of his now famous R test for disease D. Disease D has a prevalence of 16% in the population. Test R1 has a sensitivity and specificity of .82 and .87, respectively. Test R2 has a sensitivity and specificity of .83 and .91, respectively. Given this information, what is the net sensitivity [answer1] and the net specificity [answer2] of the combined tests? Note, use the addition and multiplication rules to complete this problem, and assume simultaneous testing.
