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

Using the Chi-Square test for the difference between two proportions, determine (α=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:
