For each of the following (separate) sets of data, compute the values needed in order to fill in the answer spaces. Then answer the additional questions that follow.

(Use the appropriate summation rule in each case so as to make the calculations easier.)

Data set 1: N = - = - (- -)- - () - +Y)- 1 3 3 4 2 3 Data set 2: N =. . ( - + )- - - (- - -y )= 7.14 8.00 2.60 4.32 3 2.00 4 4.00 5 4.00 6.00 1.15 1.00 2.25 1.00 10.00 3.00 set 1 set 2 If every X score is multiplied by 3.2, what is the new X in each set? If 7 is subtracted from every Y score, what is the new DY in each set? If 1.8 is added to every X score, what is the new X in each set? If every Y score is divided by 4, what is the new EY in each set?
