Question 174695
The following table provides the average cost per No-fault Clain in NYS. 
Year Average Cost
1990 $3,360
1991 $3,788
1992 $4,197
1993 $4,396
1994 $4,623
1995 $4,862 
1996 $4,969
1997 $5,675
1998 $6,064 
1999 $6,700 
Part...
(a) Determine the linear and exponential functions that best fit this data. (Remember to let t=0 represent 1990.) 
Linear Regression Eq: y = 335.39x + 3354.13; R-value = 0.9821...
Exponential Regress Eq: y = 3489.42(1.0717..)^x ; R-value = 0.9886
-------------
Since the R-value with the Exponential is greater than the R-value with
the Linear, the Exponential is a better model.

Note: I used a TI-83 graphing calculator to generate the reqression equations.
