Data originally from DASL http://lib.stat.cmu.edu/DASL/Datafiles/CancerSurvival.html (Links to an external site.). 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 from 200 days? CANCER SURVIVAL Report an appropriate one-sample hypothesis test and use a 10% significance level. For Step 5 of the six-step process that was taught in this class, do the appropriate procedure on your calculator and then choose the correct P-value. Group of answer choices 0.195 0.377 0.805 0.609 0.391

CANCER SURVIVAL Report an appropriate one-sample hypothesis test and use a 10% significance level. For Step 5 of the six-step process that was taught in this class, which would be the appropriate procedure and why?  Choose the correct option. Group of answer choices We would do a t-procedure because we have the standard deviation. We would do a t-procedure because the sample size is large. We would do a t-procedure because we do not have the population standard deviation and…

CANCER SURVIVAL Report an appropriate one-sample hypothesis test and use a 10% significance level. For Step 6 of the six-step process that was taught in this class, what would be the final conclusion? Group of answer choices The P-value is low so we cannot conclude that the average survival time is significantly different from 200 days. The P-value is not very low so we cannot conclude that the average survival time is significantly different from 200 days. The P-value is not…
