Problem 2 Problem 3 (14 points) Problem 4 Reflexology and Breast Cancer ~ A recently published journal article describes a study conducted by MSU researchers. The researchers recruited 256 women living in the Midwest who were undergoing Problem 5 treatment for breast cancer. Prior to the study, each patient was asked to identify a friend or family member (called the caregiver) who was willing to learn how to deliver a foot reflexology session and perform the session at least once per week for four weeks At the beginning of the study, all 256 patients were interviewed by trained data collectors via telephone. Data collectors recorded the age, race, ethnicity, level of education, employment income, and their relationship to their caregiver. They also recorded responses to questions evaluating their depressive symptoms and the severity of 13 medical symptoms such as pain, fatigue, nausea, dry mouth, etc. Symptoms were rated as mild, moderate, or severe. After the first interview, half of the patients were randomly assigned to receive reflexology sessions from their caregiver and the other half were not. These caregivers were instructed in the technique by trained reflexologists. All patients received weekly phone calls from the data collectors where they were asked about their symptoms. Patients had a limited amount of social interaction with the interviewer. Results of the research showed a decrease in the reported amount of pain for patients in the reflexology group, while other symptoms were not noticeably different between the two groups. 1. What is the research question for this study? O A. Can friends and family members of breast cancer patients learn to perform reflexology sessions? O B. Are race, age, and level of education related to the effectiveness of reflexology sessions and weekly telephone calls? O C. Do reflexology session reduce the severity of symptoms for breast cancer patients? O D. Do weekly telephone calls reduce the severity of symptoms for breast cancer treatments? 2. Consider the study above. Match each statistical term to the appropriate aspect of the study. Note, you won't use all the available phrases from the right column. ? v 1. Population of interest A.
