12. a) y = -x +1

13). d) y = -2x - 7/2

14). a) y = x

15). no correlation

16). a) y = x - 4

17). No correlation

18).

Interpolation -

We could use our function to predict the value of the dependent variable for an independent variable that is in the midst of our data.

Extrapolation -

We could use our function to predict the value of the dependent variable for an independent variable that is outside the range of our data. In this case, we are preforming extrapolation.

19).

a). For year 1992, x = 4

y = 55x + 126

=> y = 55 * 4 + 126 = 346

b). Linear interpolation

c). For year 2000, x = 12

=> y = 55 * 12 + 126 = 786

d). Linear extrapolation

20).

a). For yearr 1997, x = 12

=> y = 0.25 * 12 + 4 = 7

b). Extrapolation

c). For year 1991, x = 6

=> y = 0.25 * 6 + 4 = 5.5

d). Interpolation
