The procedure used for this test is two-sample z test for proportions

Step-by-step explanation:

The two sample z test is a hypothesis test that is used to compare two sample groups to determine if they have originated from the same population.

It is a statistical test used to determine whether two population means are different especially when the variances are known and the sample size is large.
