The Medical Rehabilitation Education Foundation reports that the average cost of rehabilitation for stroke victims is 24,735. To see if the average cost of rehabilitation is different at a particular hospital, a researcher selects a random sample of 38 stroke victims at the hospital and finds that the average cost of their rehabilitation is 24,205. The standard deviation of the population is $3251. Find the value of Z in order to make a suitable claim with a given critial value

Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
