Essay

Your textbook presented you with the following regression output:  TestScore =698.92.28×STRn=420,R2=0.051,SER=18.6\begin{array} { l } \text { TestScore } = 698.9 - 2.28 \times S T R \\n = 420 , R ^ { 2 } = 0.051 , S E R = 18.6\end{array} (a)How would the slope coefficient change, if you decided one day to measure testscores in
100s, i.e., a testscore of 650 became 6.5? Would this have an effect on your
interpretation?
