Researchers examined how height was related to lung vital capacity in humans.
Vital capacity is the largest volume of air that can be forced out of the lungs after a person has taken the deepest breath possible.
Table 3.1 gives the findings from the study.
(a(i))[4]
Use the data in Table 3.1 to draw a line graph on the grid.
(a(ii))[1]
Describe the relationship your graph shows between height and vital capacity.
(a(iii))[2]
Use your graph to estimate the vital capacity of a person who is $175$ cm tall. Show on your graph how you reached your estimate.
(b)[1]
State the name of the reagent used to test for protein.
