Pregunta:
When should we use the Student’s t-distribution instead of the normal distribution?
Autor: Henriette BergoRespuesta:
The Student’s t-distribution is used when the sample size is small (less than 30) and the population standard deviation is unknown. It adjusts for the extra uncertainty with small samples.
