Document Summary
The average number of units earned per semester by college students is suspected to be rising. A researcher at boston college wishes to estimate the number of units earned by students during the spring semester of 2004 at boston. To do so, he randomly selects 250 student transcripts and records the number of units each student earned in the spring term of 2004. The classification of student major (accounting, economics, management, marketing, other) is an example of: a categorical random variable, a discrete random variable, a continuous random variable, a parameter. A study is under way in national forest to determine the adult height of pine trees. Specifically, the study is attempting to determine what factors aid a tree in reaching heights greater than 50 feet tall. It is estimated that the forest contains 32,000 adult pines. The study involves collecting heights from 500 randomly selected adult pine trees and analyzing the results.
