Student Project Figures Figure 3 Figure 3: Mucus volumes produced in each treatment (mm3). Thick lines of boxplots represent medians. Lower and upper edges of boxes represent 25% and 75% quartiles, respectively, so that 50% of the mucus volume values in each treatment are comprised into each box. Extreme lower lines at the ends of dashed vertical lines represent less than 25% of the mucus volume values for each treatment. Figure 3 Figure 4
