What is the measure of survival analysis that is the average survival time for a group of patients? A. predictive value B. survival rate C. survival time D. case-fatality rate
Homework Answers
Answer: (C) survival time ( Survival analysis is a branch of statistics for analyzing the expected duration of time until one or more events happen, such as death in biological organisms and failure in mechanical systems.Median survival is a statistic that refers to how long patients survive with a disease in general or after a certain treatment)

Use the information below to answer the CANCER SURVIVAL questions that follow. Data originally from DASL http://lib.stat.cmu.edu/DASL/Datafiles/CancerSurvival.html e. Some bronchial cancer patients had the following survival times (in days) after receiving a certain treatment: 20, 37, 63, 64, 72, 81, 138, 151, 155, 166, 166, 223, 245, 246, 450, 459. (The second instance of "166" is not a mistake.) Do these numbers suggest that the average survival time, for all bronchial cancer patients who receive that treatment, is significantly different...

1. Calculate the survival rate for each group in figure 1. Use
the following formula: percent survival= (surviving
rabbits/#beginning rabbits) *100
For example, if a group had began with 10 rabbits and only 3
survived, the percent survival would be 3/10 *100 or 30%. Which
group has the highest survival rate? Which group had the
lowest?
2. Use your results to write an overall conclusion to the
Rabbit Island Experiment. Also develop an answer to each of Dr.

Q. A hospital has an average of 15% fatality rate for patients admitted due to myocardial infaraction. They perform a clinical study with a control chart and 3sigma limits. Assuming they monitor 40 patients every month, what are the lower and upper control limits. After setting up new treatment practices, the hospital wants to find out if there is 10% reduction in the fatality rate. How large sample size is needed so that they can detect that improvement with atleast...
