Question 21

You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.
