After more studies, it was found that the smartwatch monitoring for atrial fibrillation has a sensitivity of 81% and a specificity of 97% for predicting whether a person, aged 60 and older, is experiencing atrial fibrillation. It is known that the prevalence of atrial fibrillation in the population of adults 60 and older is 3%. Note: numbers in this question do not reflect reality. a. [2 marks] What is the probability that patient suffers from atrial fibrillation if smartwatch indicts that they are suffering from atrial fibrillation. Assuming all numbers given in the above paragraph are correct? Give the probability as a decimal to 4 decimal places PO= b. [1 mark] Give the probability of a false positive. P()= c. [2 marks] Create a 2x2 table similar to Table 4-2 in the text assuming you have a total of 100,000 subjects Smart watch prediction of Atrial Fibrillation Positive Test Negative Test Total Atrial Fib. No Atrial Fib. Total 100000 d. [2 marks] What is the probability that a patient suffers from atrial fibrillation if smartwatch indicts that they are suffering from atrial fibrillation assuming that we only consder the subpopulation of people who have a family history of heart disease where the prevalance of atrial fibrillation is the higher value 25%? Give the probability as a decimal to 4 decimal places PO=
