Find the equation of the least-squares line for the stride length and speed of camels given in the table below.
Stride Length (m) 2.5 3.0 3.2 3.4 3.5 3.8 4.0 4.2
Speed (m/s) 2.3 3.9 4.1 5.0 5.5 6.2 7.1 7.6
Use the equation of the least-squares line from to predict the average speed (in meters per second) of a camel with a stride length of 3.9 meters. Round your results to the nearest tenth of a meter per second. (See Example 2 in this section.)
