One of the crises within the healthcare system is the use of emergency rooms, where many people go for primary care instead of going to a typical doctor, particularly if they don’t have health insurance. Using the PewHealth dataset, run a logistic regression model that uses the recoded ER-usage variable as your dependent variable. For your independent variables, first use just the recoded income variable; then, add the dichotomously recoded insurance variable. Create a table that includes both models. Tell the story of what is going on in this set of nested models by running four examples:

a. someone whose family income is $10,000 and he or she doesn’t have health insurance

b. someone whose family income is $10,000 and he or she does have health insurance

c. someone whose family income is $150,000 and he or she doesn’t have health insurance

d. someone whose family income is $150,000 and he or she does have health insurance
