A test for the disease has sensitivity of 97% and specificity of 87%. (a) Create a hypothetical one hundred thousand table illustrating this situation, where the row categories are disease (yes, no) and the column categories are test results (positive, negative). Test Result Positive Negative Total Disease No Disease Total (b) Calculate the probabilities labeled on the tree diagram below. (Give answers correct to five decimal places.) a = b= C= 티비티 d= e = h = p= n = S = U= Final probability Positive test p C Disease d Negative test All Positive test S h No disease h Negative test U (c) Using the table from part (a) or the tree diagram from part (b), find the proportion of people who will test positive for the disease.
