1. Copy and paste the data into a statistical software package and determine the equation of the least squares line. Round your values for the slope and y-intercept to 2 decimal places. Temp = x Chirps + 2. What is the meaning of the slope of the least squares line? O If the chirp rate of the crickets increases by 2.9837 chirps per second, then the temperature has increased by 1° F. O If the chirp rate of the crickets increases by 1 chirp per second, then the temperature has increased by 30.0683° F. O If the chirp rate of the crickets increases by 30.0683 chirps per second, then the temperature has increased by 1° F. O If the chirp rate of the crickets increases by 1 chirp per second, then the temperature has increased by 2.9837° F. 3. Use the least squares line to predict the temperature if the crickets are chirping at a rate of 18.8 per second (round your answer to 1 decimal place). 4. What is the residual for the first cricket in the data set (round your answer to 1 decimal place)? 5. What percentage of the variability in temperature can be explained by the chirp rate? (Round your answer to 1 decimal place).

![Pierce measured the number of chirps per second for the striped ground cricket at various temperatures.
Since crickets are ectotherms, their metabolism is affected by temperature and it was found that the
crickets did not sing at temperatures below 60° F or above 100° F.
