In 1993, the life expectancy of males in a certain country was 67.2 years. In 1999, it was 70.3 years. Let E represent the life expectancy in year t and let t represent the number of years since 1993.

The linear function E(t) that fits the data is E(t)=_t + _.

(Round to the nearest tenth)

Use the function to predict the life expectancy of males in 2009.

E(16)= _

(Round to the nearest tenth)
