Each Time Your Heart Beats, Your Blood Pressure Increases, Then $p ( t ) = 120 + 25 \sin ( 150 \pi t )$

question 93

Essay

Each time your heart beats, your blood pressure increases, then decreases as the heart rests between beats. A certain person's blood pressure is modeled by the function $p ( t ) = 120 + 25 \sin ( 150 \pi t )$ , where $p ( t )$ is the pressure in mmHg, at time t measured in minutes.
(a) Find the amplitude, average pressure between beats, the maximum and minimum blood pressure, period, and frequency of p.
(b) Sketch the graph of p.

Definitions:

Null Hypothesis

A hypothesis that suggests there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.

Standard Error of the Mean

A statistical measure that estimates the sampling variability of the mean from different samples drawn from the same population.

Standard Error of the Mean

The standard deviation of the sampling distribution of the mean, showing how much the sample mean is expected to vary from the true population mean.

Population Averages

The mean value of a particular characteristic in a population, representing the central tendency of that characteristic across the entire population.
