[Answered] A student does an experiment for a science fair to study whether temperature affects the timing of a cricket's chirps. The student keeps a cricket in an enclosed box that is heated to different temperatures each day for twelve days. The student records the cricket's chirps by using a sound-activated microphone so that the timing of the chirps can be measured. The student records the results of the experiment in the table below. | Day | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Temperature ($^{\circ}C$) | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | | Average time between chirps (sec) | 2.5 | 2.6 | 2.2 | 2.3 | 2.0 | 1.8 | 1.9 | 1.8 | 1.4 | 1.2 | 1.5 | 1.1 | Which generalization can be made from the data in the table? A. The higher the temperature, the fewer chirps there will be in 10 seconds. B. The chirps occur closer together as the temperature increases. C. The chirps become farther apart as the temperature increases. D. There is no relationship between temperature and the time between chirps.
