The Social Security (FICA) wage base (in thousands of dollars) from 1996 to 2001 is given in the accompanying table:
Find an equation of the least-squares line for these data. (Let x = 1 represent the year 1996.) Please round the coefficients
in your equation to three decimal places. Use the result to estimate the FICA wage base in the year 2005.
a. y = 3.587x + 58.368; $94,238
b. y = 3.574x + 58.440; $94,405
c. y = 3.574x + 58.440; $94,180
d. y = 3.587x + 58.368; $94,132
c. y = 3.574x + 58.440; $94,180
