question 102

Multiple Choice

Researchers conduct an experiment to determine hemodynamic changes during exercise.  Invasive monitoring of various parameters is performed to obtain a left ventricular pressure-volume loop.  Compared to at rest, which of the following changes is most likely to be observed during moderate to heavy exercise?(solid line: at rest; dashed line: during exercise)

Definitions:

Confidence Interval Estimate

A confidence interval estimate provides a range of values, derived from sample data, that is likely to contain the value of an unknown population parameter, along with a given level of confidence.

Prediction Interval

A range of values that is likely to contain the value of an unknown parameter for a future observation, with a specified level of confidence.

Expected Value

In probability and statistics, it is the average value obtained from numerous trials of an experiment over an extended period.

Confidence Interval

A compilation of values, resulting from the statistical study of samples, aimed to likely capture the value of an unknown population parameter.
