Question

in 1994 the life expectancy of males in a certain country was 70.1 years . in 1998 it was 72.8
the linear function E )t) that fits the data is
e(t)
now with the function predict the life ex[ectancy of males in 2003
E(9)

Answer 1

If you assume 1994 is x = 0, and 1998 is x = 4, you can get the equation:

e(t) = 70.1 + 0.675t

e(9) = 76.175
