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...

1. What is the difference between a test of independent means and a test of matched means? 2. How would I calculate a test of matched means? what is the“matched” means? 3. Do you think both these tests ( a test of independent means and a test of matched means) are reasonable? Fair? Why or why not? Common concerns might be assumptions of the test being met, the practicality of the test, etc.

Suppose a test is performed to test H0: risk difference = 0 versus H1: risk difference ≠ 0, and the test rejects H0 at α = 0.05.

Part 1. Suppose a test is performed to test H0: risk difference = 0 versus H1: risk difference ≠ 0, and the test rejects H0 at α = 0.05. Then, we can conclude that there is real significant evidence (α = 0.05) of a difference in proportions, _____________________ evidence that the risk difference is not 0, and _____________________ evidence that the relative risk and odds ratio are not _________________. Choose between significant, not significant, 0, 1. Part 2. Contrast...
