What was your recorded resting breathing rate (sitting position)?

Based    on    the    plot    you’ve    constructed:1. What    relationship    did    you    find    between    height    and    vital    capacity?2. What    might    be    the    explanation    for    this    relationship?3. How    might    these    changes    in    size    be    explained?4. What    factors    may    be    contributing    to    the    variation    observed

A student undertakes a project to determine the effect of carbon dioxide on respiration rate using the following methodology. A volunteer inhaled air from a bag containing a predetermined amount of carbon dioxide (with partial pressure in torr) and the number of breaths per minute was recorded. Her data are given below: Partial pressure CO2 (torr) Respiration rate (breaths/minute) 30 8.1 32 8.0 34 9.9 36 11.2 38 11.0 40 13.2 42 14.6 44 16.6 46 16.7 48 18.3 50 18.2                   Choose the best statistical test for this study.   a. Correlation   b. Simple Linear Regression   c. Non-Linear Regression   d. General Linear Model Regression

Some Events Related to Breathing 1 increased rate of breathing 2 Nervous stimulation of the diaphragm 3 Increased concentration of CO 2 in the blood 4 Decreased concentration of CO 2 in the blood 5 Chemical stimulation of the respiratory centre   The sequence of events that occurs as the breathing rate is increased Is   a) 3,5,2,1 and 4 b) 5,3,1,2 and 4 c) 3,2,4,1 abd 5 d) 4,3,5,2 and 1
