A collection of paired data consists of the number of
years that students have studied Spanish and their scores on a
Spanish language proficiency test. A computer program was used to
obtain the least squares linear regression line and the computer
output is shown below. Along with the paired sample data, the
program was also given an x value of 2 (years of study) to be used
for predicting test score.
Equation: y = mx +

The following regression model is used to predict a student's
grade in their final test:
Grade = B0 + B1 Study Hours +
B2 Sleep Hours + B3 Tutoring + e
Where:
Grade = score on test out of 100
StudyHours = hours studied in the week before the test
SleepHours = hours slept the night before the test
Tutoring = whether of not the student went to tutoring before
the test (not attending tutoring is the omitted condition)
