In 1995, the life expectancy of males in acertain country was 67.5 years. In 2002, it was 70.8 years. Let E represent the life expectancy in year t and let t represent the number of years since 1995. The linear function E(t) that fits the data is E(t)=?t+?. Use the function to predict the life expectncy of males in 2003. E(8)=
