The Regression Equation · Try It 1

SCUBA divers have maximum dive times they cannot exceed when going to different depths. The data in show different depths in feet, with the maximum dive times in minutes. Use your calculator to find the least squares regression line and predict the maximum dive time for 110 feet.

$$\begin{array}{cc}\text{x (depth)}& \text{y (maximum dive time)}\\ \text{50}& \text{80}\\ \text{60}& \text{55}\\ \text{70}& \text{45}\\ \text{80}& \text{35}\\ \text{90}& \text{25}\\ \text{100}& \text{22}\end{array}$$
