Question 321195
The ages (in years) of seven people and the number of days they spent recovering in the hospital after surgery are given in the following table. 
Age, x 12 21 38 44 59 63 70 
Days in Hospital, y 4 6 7 5 9 11 12 
Using the regression line, predict the value of y for x = 30.

Equation:
f(x) = 0.1248x+2.242
---
f(10) = 3.49
