Using the z-distribution, as we are working with a proportion, it is found that the test statistic for their significance test is given by: z = 2.
<h3>What are the hypothesis tested?</h3>
As stated in the problem, they are:
<h3>What is the test statistic?</h3>
It is given by:
In which:
- is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, we have that;
