Question 2: The attached Excel file named “Question 2.xls” includes the raw data and the example of computing Kaplan-Merier (KM) estimation of survival analysis. In this file, the sheet “Control Group” shows the example of calculating KM for the control group. Also this sheet shows the computation of the annual expected cost. Please use this file to conduct analyses and answer the following answers.
Please apply the KM technique to the dataset of treatment group. Then generate the line graph comparing the survival curves of both control and treatment groups. Please copy and paste the line graph in the below space. Does the treatment improve the survival of patients? (10 points)
