Question

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 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 very low so our conclusion is that the average survival time is significantly different from 200 days.

The P-value is low so our conclusion is that the average survival time is significantly different from 200 days.
