(20 POINTS) The graph represents the atmospheric pressure, in ounces per square centimeter, as a function of altitude in kilometers above sea level.

Which statements accurately reflect this relationship?
As the altitude decreases, the atmospheric pressure increases
As the altitude continues to increase, the atmospheric pressure approaches 0 oz/cm^2 .
The atmospheric pressure is 0 oz/cm^2 at sea level
The atmospheric pressure gets close to 36 oz/cm^2 as the altitude continues to increase

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
