Question

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 (ºC) 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 conclusion can be made from the data in the table? The higher the temperature, the fewer chirps there will be in 10 seconds. The chirps occur closer together as the temperature increases. The chirps become farther apart as the temperature increases. There is no relationship between temperature and the time between chirps.

Answer 1

The cricket's chirps occurred closer together as the temperature increased, implying a positive correlation between temperature and chirping frequency.

Step-by-step explanation:

The student's experiment aimed to measure the relationship between temperature and the timing of a cricket's chirps. According to the data collected, as the temperature increased from 21 °C to 32 °C, the average time between the cricket's chirps decreased from 2.5 seconds to 1.1 seconds. This indicates that the crickets chirped more frequently at higher temperatures, or in other words, the chirps occurred closer together as the temperature increased.
