Answer:

The sample size is too small

Step-by-step explanation:

The answer is the last one: the sample size is too small. Since we only got 3 subjects to test, maybe one of them could live for a long time after the diagnosis of Cacer and that made the average survival time go up by a lot.

In order to obtain results with a significance level higher, you need a sample size of at least 20 subjects.

Now lets see why other options wouldnt be good answers:

  • For a small amount of subjects, it is unlikely to have errors in caculation
  • The sample size is given
  • We are not given information about the treatment and we dont even know if the subjects feel more confident with the new treatment. Also, if a Placebo effect works regularly, it shouldnt limit statistical sifgnificance
  • An increase in 2 years is huge in comparison with the previous survival time.
