We need to solve the Key Problem from the beginning of the lesson.
This asked if you could tell what the temperature was from the number of chirps per second the crickets make.
Using the method in this lesson, find the equation of the line which gives the lowest mean square error.
This will give you the ability to estimate the temperature from a given number of chirps per second.
Your answer should be one the following:
Good luck. Work with your class and share ideas.
When you are done go to the next problem.
