Samantha works for a healthcare company. She is currently conducting research focused on patient recovery times in different hospital departments, specifically examining whether the mean recovery time for patients in the cardiology department is significantly longer when compared to the mean recovery time for patients in the orthopedics department. Let C denote the mean recovery time for patients in the cardiology department. Let o denote the mean recovery time for patients in the orthopedics department. What is the appropriate alternative hypothesis that Samantha should specify to test her specific hypothesis of interest? Oa: (C - O) 0 Ha: (uC - uO) 0 Ha: (CO) > Ha: ( O) <0
