Medical researchers noticed that when the amount of the active ingredient within a patient’s allergy medicine is increased, the patients taking that medicine report higher levels of relief from their allergy symptoms. The data in the table show various levels of the active ingredient (in milligrams) and a score (from 0 to 10) indicating the level of allergy relief experienced for a sample of patients. A 2-column table with 16 rows. Column 1 is labeled Active ingredient (milligrams) with entries 2, 2, 3, 3, 3, 5, 5, 5, 5, 5, 8, 8, 10, 10, 10, 10. Column 2 is labeled Relief score with entries 5.6, 5.7, 7.3, 7.5, 7.6, 7.7, 8.2, 8.5, 8.9, 7.9, 9.2, 8.3, 8.9, 8.8, 10.0, 9.0.
