La temperatura bajó 12 °
Explicación paso a paso:
Dado que:
Temperatura en la noche = + 2 ° (2
Temperatura de la mañana = - 12 (12 ° bajo cero).
La diferencia de temperatura entre la noche y la madrugada:
Temperatura nocturna - temperatura por la mañana temprano

Hay una diferencia de temperatura de 12 °. La temperatura bajó 12 ° entre la noche y la madrugada.
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.
