I am very confused. When performing a linear regression model How are you supposed to compare the number of hospital beds and ownership. This is the table my professor gave me:

Model 1.Run a linear model to predict the impact of difference in hospital beds (use the total hospital beds column) and hospital's ownership on hospital net benefit.

Hospital Characteristics Coef. St. Error

Hospital beds

Ownership

For-Profit

Not-for-profit

Other

N

R Squared

My question is how am I suppose to get the standard error and coefficient for all of these categories when I'm suppose to be comparing their variables? Wouldn't I only get 1 number for each comparison?
