The answer is the second one: Stroke volume x Heart beat rate.

Explanation:

  • Stroke volume / Heart beat rate: This would give a value that does not represent cardiac output. It would be a measure of volume per beat divided by the number of beats, which is not meaningful in this context.
  • Stroke volume x Heart beat rate: This is the correct formula for cardiac output. Cardiac output is the volume of blood the heart pumps per minute, which is calculated by multiplying the volume of blood pumped per beat (stroke volume) by the number of beats per minute (heart beat rate).
  • Heart beat rate / Stroke volume: This would give a value that is the inverse of stroke volume per beat rate, which is not relevant to cardiac output.

Summary: Cardiac output is equal to Stroke volume x Heart beat rate.

Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. Assume the population of interest is the student body at a university. Questioning students as they leave an academic building, a researcher asks 338 students about their eating habits. What type of sampling is used? A. Convenience sampling is used, because students are chosen due to convenience of location. B. Systematic sampling is used, because students are selected from a list, with a fixed interval between students on the list. C. Simple random sampling is used, because students are chosen at random. D. Stratified sampling is used, because students are divided into groups, and students are chosen at random from these groups. E. Cluster sampling is used, because students are divided into groups, groups are chosen at random, and every student in one of those groups is sampled. What potential sources of bias are present, if any? Select all that apply A. University students may not be representative of all people in their age group. B. The sample only consists of members of the population that are easy to get. These members may not be representative of the population. C. Because of the personal nature of the question, students may not answer honestly. D. There are no potential sources of bias. Get more help Clear all
