Canine Heartworm Disease (CHD) caused byDirofilaria immitiscontinues to be a commonly diagnosed parasitic disease in the United States.There is a new method for detecting whether or not a dog has heartworms that can be administered at home. For dogs that are infected with heartworms, the test has a 90% chance of detecting it (a positive test result). For dogs that do not have heartworms, the test will correctly produce a negative result 80% of the time. You are implementing the test on a population of dogs where 80% do not have heartworms.

What is the probability that a dog that tests positive with this new method actually has heartworms? Answer as a proportion and round to 2 decimal places (answers within +/- 0.02 will get full credit).
