Spanish term or phrase: contraste de igualdad de proporciones

In a text I'm editing, the writer left this term in Spanish.

The indication for use category (on label, off-label and untested use) was evaluated using the Chi-square test and the __contraste de igualdad de proporciones__.

Other examples of the same term found include:

Las diferencias regionales en temporalidad son estadísticamente significativas como se desprende de
un __contraste de igualdad de proporciones__.

Tema 14. Contrastes de hipótesis con dos muestras.
Contraste de igualdad de medias. __Contraste de igualdad de proporciones__. Contraste de igualdad de
varianzas.

(a) Haz el contraste de hipótesis que hubieras hecho al finalizar la asignatura de Estadística II.
Observa que el número de observaciones en algunas casillas hace muy poco sostenible el empleo
de una aproximación normal, sin embargo. ¿Qué pobs obtienes?
Respuesta: El contraste que hubiérais hecho al finalizar Estadística II sería probablemente
un __contraste de igualdad de proporciones__ de intoxicación en las subpoblaciones que han
tomado mayonesa (porporción p1) y que no lo han hecho (proporción p2). Lo natural sería
haber adoptado como alternativa
Ha: p1 > p2: aunque el enunciado es deliberadamente
vago, claramente no esperamos que la mayonesa haya actuado como antídoto de la intoxicación,
sino que de haber alguna influencia, la suponemos perniciosa. (Planteamientos
diferentes no obstante se hacen acreedores a puntuación total si han sido claramente explicitados.)

testing equality of proportions

Explanation:
I have both the English and the Spanish versions of Introductory Statistics, by S. M. Ross, and point 10.6 is titled "contraste de igualdad de proporciones poblacionales" and "Testing Equality of Population Proportions".

The term "testing equality of proportions" on its own is also very widespread.
