A two proportion z-test allows you to compare two proportions to see if they are the same. The null hypothesis (H0) for the test is that the proportions are the same. The alternate hypothesis (H1) is that the proportions are not the same.
What are the 4 conditions for a 1 proportion Z interval?
In order to conduct a one-sample proportion z-test, the following conditions should be met: The data are a simple random sample from the population of interest. The population is at least 10 times as large as the sample. n⋅p≥10 and n⋅(1−p)≥10 , where n is the sample size and p is the true population proportion.
What does a 2 sample z-test show?
The Two-Sample Z-test is used to compare the means of two samples to see if it is feasible that they come from the same population. The null hypothesis is: the population means are equal.
