A
student at a junior college conducted a survey of 20 randomly
selected full-time student to determine the relation between the
number of hours of video game playing each week, x, and grade-point
average, y. She found that a linear relation exists between the two
variables. The least-squares regression line that describes this
relation is y= -0.0559x + 2.9205
(a) Predict the grade-point average of a student who plays
video games 8 hours per week
(b) Interpret the slope.
(c) If appropriate, interpret the y-intercept
(d) A student who plays video games 7 hours per week has a
grade-point average of 2.64. Is the students grade-point average
above or below average among all students who play video games 7
hours per week?

Q4. Professor Video, a college psychology instructor, wants to
determine if there is a negative linear correlation between
a student’s GPA and the number of hours a student spends playing
video games per week. She randomly selected twenty
students from all her classes and determined their number of hours
playing video games per week and their GPA. The
sample results were:
GPA: 4.00 2.50 3.95 3.90 3.80 2.90 3.10 3.25 1.35 4.00

9. A lot of corn grows in Iowa. For several years, farmers have
kept track of the amount of rainfall (in inches) and the amount of
corn produced (in bushels per acre). A strong and linear
relationship has been observed between these variables. When a
regression equation is constructed in order to predict amount of
corn produced based on rainfall, it is found that the equation has
an intercept of 89.54 and a slope of 0.13. We can conclude from...
