A scientist designed an experiment to examine the effects of exercise on respiration. He collected the volume of the gases produced by a group of people as they were running, walking, and at rest for 5 minute time periods.
Which question can the scientist answer with his experiment?
a
Does the amount of oxygen produced during physical activity depend on time?
b
Does the amount of time spent being active affect the volume of carbon dioxide breathed in?
c
Does increased activity lead to a higher volume of carbon dioxide produced?
d
Does decreased activity require a higher amount of oxygen than increased activity?
c
Does increased activity lead to a higher volume of carbon dioxide produced?
c
Does increased activity lead to a higher volume of carbon dioxide produced?
The scientist can answer the question "Does increased activity lead to a higher volume of carbon dioxide produced?" based on the data collected during the experiment.
To get the answer to this question, the scientist can analyze the volume of carbon dioxide produced by the group of people during different activities (running, walking, and at rest) for 5-minute time periods. By comparing the volume of carbon dioxide produced during different activities, the scientist can determine whether increased activity leads to a higher volume of carbon dioxide produced.
The scientist can also use statistical analysis to determine if the observed differences in carbon dioxide production during increased activity are statistically significant. Additionally, the scientist should account for any potential confounding variables, such as age, gender, and fitness level, that may influence the results and findings of the experiment.
