You may want to create a table to help you with this problem. Consider a computer test to indicate if you like Math 123 or dislike Math 123. If positive, you like the class and if negative you dislike the class. In a sample of 25 thousand people, 80% of the population indicated they liked the class. If the test is 85.5% accurate, what are the chances that the test showed the person disliked Math 123, but in reality they actually liked the course? Round your percentage to 2 decimals.
