Data Sets for Kutner et al.
Data sets from Chapter 1
Data for Problem 19 Grade Point Average. The director of
admissions of a small college selected 120 students at random from the new freshman
class in a study to determine whether a student’s grade point average (GPA) at
the end of the freshman year (Y) can be predicted from the ACT test score (X).
Data for Problem 20 Copier Maintenance. The Tri-City Office Equipment Corporation sells an imported copier on a franchise basis and performs preventive maintenance and repair service on this copier. The data set consists of 45 recent calls on users to perform routine preventive maintenance service; for each call, X is the number of copiers serviced and Y is the total number of minutes spent by the service person.
Data for Problem 22 Plastic hardness. Experience with a certain type of plastic indicates that a relation exists between the hardness (measured in Brinell units) of items molded from the plastic (Y) and the elapsed time since termination of the molding process (X). There was a total of 16 batches of the plastic made and from each batch one test item was molded.
Data for Problem 27 Muscle mass. A person’s muscle mass is expected to decrease with age. To explore this relationship in women, a nutritionist randomly selected 15 women from each 10 year age group, beginning with age 40 and ending with age 79. In this data set, X is age and Y is a measure of muscle mass.
Data for Problem 28 Crime rate. A criminologist studying the relationship between level of education and crime rate in medium-sized U.S. counties collected the following data for a random sample of 84 counties: X is the percentage of individuals in the the county having at least a high-school diploma, and Y is the crime rate (crimes reported per 100,000 residents) last year.
