The book Day Hikes in San Luis Obispo County lists information about 72 hikes, including the distance of the hike (in miles), the elevation gain of the hike (in feet), and the time that the hike is expected to take (in minutes). Consider the scatterplot below, with least squares regression line superimposed: 400 - Predicted time (min) = -1.266 + 31.48 distance (mi) 300 - Time (min) 200 - 100 0 0 N 6 8 10 Distance (mi)
