Study

    

  1. The population of interest is the student body of North Olmsted High School.  The Sample was derived from a list of every student that attends NOHS with a corresponding number for their alphabetical placement.  The list of students was placed into a random number generator through the use of the Minitab program.  The program was used to obtain a random list of 100 students to be surveyed for our project.  The 100 randomly selected students are the sample to be used and include students from all grades and both genders from the school student list.

We used random and independently chosen samples.  We can assume normality since students sampled>30 and follows the central limit theorem.
