The number of hours spent online during a weekend and the score
on the test on the following Monday for each of 12 students are
given below hours spent online(x) 0 1 2 3 3 5 5 5 6 7 7 10 Test
scores (y) 96 85 82 74 95 68 76 84 58 65 75 50 1. Suppose the
regression line for the above ( hours online and scores on test)
data is: LaTeX: /hat y = -4.07 x +
93.97y^=−4.07x+93.97y^=−4.07x+93.97 . What would you predict to be
the test score for a student who spend 9 hours online during the
weekend prior? 2. In the equation of the regression line LaTeX:
/hat y = -4.07 x + 93.97y^=−4.07x+93.97y^=−4.07x+93.97 if x
increases by one unit, then
