Researchers were interested in whether telephone follow-up had an impact on health- related quality of life (HRQoL) in cancer patients receiving cancer therapy. The follow-up telephone call gave patients an opportunity to discuss medications and to seek advice on management of symptoms. The Physical Functional Assessment of Cancer Therapy Scale (PFACT) tool was used to measure HRQoL. The data collected. in the study are in the excel file called PFACTlocated in the Data folder of A2L Contents. These data show the baseline PFACT score and the follow-up score for telephone follow-up conducted 72 hours after discharge from hospital for 66 patients receiving cancer therapy. Use these data to answer the questions below. < a. Conduct the appropriate statistical test to determine whether HRQoL decreases. among patients who receive a telephone follow-up call within 72 hours following hospital discharge. Assume a=0.05. b. Calculate the 95% confidence interval for the mean difference in FACT-G scores from baseline to follow-up. c. Calculate the p-value for the test statistic used in the hypothesis test conducted in question-a Followup 19 23 25 13 25 21 22 20 19 24 15 27 26 26 28 14 17 22 22 15 23 21 11 22 17 9 16 16 20 23 17 17 6 10 16 14 - 8 8 ' + 8iR R | 19 23 20 20 10 20 20 11 22 18 6 21 17 24 15 15 9 7 24 19 22 23 3 64 22 65 17 21 66 21 26 20 25 17 18 25 | | - 8 ld 1 2 3 4 5 6 7 8 Baseline 9 12 22 34 35 36 37 38 39 40 42 43 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 , n ! 8 8 #8#6 8q # 6 @ Rdua6 8 3 ; 8 3 $ 6 8 10 11 13 14 17 18 19 20 21 22 23 24 25 26 27 28 30 31 32 33 44 45
