At a local clinic, a doctor has been receiving complaints from the nurse that the clinic needs more staff members due to the increasing number of patients.

Before the doctor makes a decision, he checks whether the number of staff members depends on the number of patients visiting the clinic. The following are the data obtained by the doctor for one day:

Staff Patients 3 45 6 30 7 21 4 39 4 41 5 30 5 23 6 20 4 32 5 33 3 38 6 25 4 28
