10.2 Written Homework 14. For the data below, r is significant. Find the equation of the regression line, and then find y when x 60 fires. Fires x Acres y 57 30 45 62 15 47 84 58 19 72 69 For the exercises below, use the same data from the questions in the 10.1 written homework. For each exercise, find the equation of the regression line and find the y value for the specified x value. Remember that no regression should be done when r is not significant. 16. Find y' when x $1500 in per capita deht 22. Find y when x- 100 days 24. Find y, when x= 30 assists. 26, Find y, when 44 stories.

Explanation / Answer

The regression equation or regression line is
Acres = - 31.5 + 1.04 Fires

Predictor Coef SE Coef T P
Constant -31.46 22.02 -1.43 0.203
Fires 1.0358 0.3498 2.96 0.025

The value of y' when x=60 fires is

Acres (60) = - 31.5 + 1.04 *60

=30.90
