To test the equality of two proportions, you would use a (n) _______ test. a. z b. t c. Chi-square d. F

To test the equality of two proportions, you would use a (n) _______ test.
a. z
b. t

c. Chi-square

d. F

Expert Solution

The option (a) is the correct.

Explanation:

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.

To test the equality of two proportions we use Z – test.

So the answer is (a).

Using the Chi-Square test for the difference between two proportions, determine (?=0.05) if there is a difference in population proportion between male patients using Medicare as their Payer versus female patients using Medicare as their Payer. Be sure to set up the null and alternate hypotheses. Using the Patients dataset, determine if there is a relationship between length of stay and total charges. Your answer should include the following: Scatter Plot Linear Regression Equation (with interpretation) Coefficient of Determination (with...

Chi Square Test We will now use Excel to run an example of a chi square test. Chi square test is checking the independence of two variables. Our example will test if taking hormonal pills and being overweight are related. We will test the independence on 200 random patients. Thus, N=200. They will be divided first into two groups, those who take hormonal pills and those who do not. Second, they will be divided into three groups based on weight,...
