The number of hours spent watching TV the weekend before a math test and the results for thirteen students in Mr. Marshall’s class are plotted below and a line of best fit is drawn. If the equation of the line is y = −5.9x +91.9,
which statement is false?
A. The slope of the line indicates that the test
score and time spent watching TV are
negatively correlated.
B. The linear model predicts an approximate
6- point drop in test score for one hour spent
watching TV.
C. The y-intercept of the line indicates that a
student who spends no time watching TV will
get the highest test score.
D. The linear model predicts an approximate
test score of 92 if no time is spent watching
TV.
