A medical item used to administer to a hospital patient is called a factor . For example, factors can be intravenous (IV) tubing, IV fluid, needles, shave kits, bedpans, diapers, dressings, medications, and even code carts. The coronary care unit at Bayonet Point Hospital

(St. Petersburg, Florida) recently investigated the relationship between the number of factors administered per patient and the patient’s length of stay (in days).

Data on these two variables for a sample of 50 coronary care patients are given in Table 10 . Use a scatterplot to describe the relationship between the two variables of interest: number of factors and length of stay.
