Problem 3 (24 points): Medical tests, such as those for COVID-19, can suffer from false alarms and misses. As a human factors specialist, you have been asked to apply signal detection theory (SDT) to investigate doctors’ abilities to detect COVID-19 using chest x-rays. You have asked 2 doctors to examine 20 chest x-rays (10 who did not have COVID-19 and 10 who did have COVID-19). Use the following data sets generated from the 2 doctors, as well as Z scores and associated ordinate values given below, to answer parts (a)–(e). State of the world (COVID-19) Doctor 1 Doctor 2 Present Not Present Present Not Present Doctor’s judgment Yes (COVID-19 present) 2 1 9 7 No (COVID-19 not present) 8 9 1 3 Total (T) 10 10 10 10
