Hookworms are parasitic nematodes that live in the intestines of a host. Hookworms do their damage (often fatally) by draining blood from the intestinal wall. The data below correlate the number of hookworms and the amount of blood lost by that number of worms. (Include units below if applicable. If necessary, use a separate sheet of paper for 6c and 7c.) Number of hookworms (x) Blood lost per day (y) 24 12.2 mL 5 2.48 cm3 45 1.37 in3 88 1.49 oz 80 39.8 cm3 63 31.5 mL 1) Inspect the data and estimate the amount of blood lost due to one hookworm.
