The correct answer to the following question will be "A one-sample z test for a population proportion".

Step-by-step explanation:

An illustration of a single sample or test Z check for population ratio or percentage is above provided experiment. We should approximate the current value of the population ratio duration where the approximately the estimated population resides. In this case, just one variable is checked so we'll have to use single sample Z.

So that the above is the right answer.
