briefly comment on the extent to which the two displacement densiometric methodologies

4. Examine Figures 3a (scatterplot) and 3b (Bland-Altman plot) below and briefly comment on the extent to which the two displacement densiometric methodologies (BODPOD and Hydrostatic Weighing) agree with each other among Fall 2022 EXSC 415 subjects. Use r, r2, B, (intercept), B, (slope) and the comparison of MeanBODPOD and MeanHaw (It)) [all in Fig 3a] and the 95%CI of the mean difference [in Fig 3b] in your answer. What are sources of error in each methodology? (1 pt) Figure 32.
