(LR-1) For this project, I will be analyzing the correlation of cricket chirps and temperature. In this study, data was collected by measuring the number of cricket chirps per second for the ground stripe cricket. The temperature, in Fahrenheit, was also monitored and recorded. The data is shown below: Chirps/second Temperature F) 20.00 88.60 16.00 71.60 19.80 93.30 18.40 84.30 17.10 80.60 15.50 75.20 14.70 69.70 17.10 82.00 15.40 69.40 16.20 83.30 15.00 79.60 17.20 82.60 16.00 80.60 17.00 83.50 14.40 76.30 Reference : The Song of Insects by Dr.G.W.

(LR-3) 14 15 16 17 18 19 20 21 65 70 75 80 85 90 95 f(x) = 3.29x + 25.23 R² = 0.7 Cricket Chirp Frequency (chirps sec-1) Temperature (ºF) Line of best fit: y = 3.2911x + 25.232 where x = chirping frequency (chirps sec -1 ) and y = temperature (ºF). (LR-4) The slope of the line is 3.2911. Since the slope is positive, the temperature is increasing at a rate of 3.2911 ºF per cricket chirp. The time interval at which the temperature is increasing cannot be determined as it is unknown as to when the researchers recorded chirping frequency.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
