Questions 8–9

A biology student is investigating the relationship between cricket chirping and air temperature. She catches a cricket and places it in a jar. She leaves the jar outside, and each day she counts the number of chirps during a 15-second period. At the same time, she records the outside temperature near the cricket. Her data for a 5-day period are shown below.

8. At which of the following temperatures would a cricket be most likely to chirp 9 times in 15 seconds?

   1. 10°C

   2. 18°C

   3. 0°C

   4. 25°C

9. What can the student conclude from this experiment?

   1. Crickets cannot chirp more than 31 times in 15 seconds.

   2. The number of times a cricket chirps decreases when the temperature decreases.

   3. The number of times a cricket chirps increases when the temperature decreases.

   4. There is no relationship between the number of times a cricket chirps and temperature.
