Spanish term or phrase: HIPOTESIS DE PARTIDA
I believe this is normally called "The Null Hypothesis"
Can someone confirm this for me with references

Explanation:
Para poder decidir sobre una hipótesis (que normalmente establecerá que existe una tendencia o relación en la población) , examinamos la contraria a la que se denomina hipótesis nula ( que establecerá que no existe tal tendencia o relación ). En cada proceso de decisión, habrán de establecerse la ***hipótesis nula o hipótesis de partida*** H0 (que es la que se contrastará), y la hipótesis alternativa H1 (sobre la que se quiere decidir) complementaria de la anterior.

***The null hypothesis***, H0, represents a theory that has been put forward, either because it is believed to be true or because it is to be used as a basis for argument, but has not been proved. For example, in a clinical trial of a new drug, the null hypothesis might be that the new drug is no better, on average, than the current drug. We would write
H0: there is no difference between the two drugs on average.

We give special consideration to the null hypothesis. This is due to the fact that the null hypothesis relates to the statement being tested, whereas the alternative hypothesis relates to the statement to be accepted if / when the null is rejected.

The final conclusion once the test has been carried out is always given in terms of the null hypothesis. We either "Reject H0 in favour of H1" or "Do not reject H0"; we never conclude "Reject H1", or even "Accept H1".

If we conclude "Do not reject H0", this does not necessarily mean that the null hypothesis is true, it only suggests that there is not sufficient evidence against H0 in favour of H1. Rejecting the null hypothesis then, suggests that the alternative hypothesis may be true
