Question
In a study of heart rate in ocean-diving birds, researchers harnessed 10 randomly sampled wild-caught cormorants to a laboratory device that monitored vital signs. Each cormorant was subjected to six artificial "dives" over the following week (one dive per day). A dive consisted of rapidly immersing the head of the bird in water by tipping the harness. In this way, a sample of 60 measurements of heart rate in diving birds was obtained. How many replicates are available to estimate the heart rate of cormorants in this population? Question 7 options: 6 10 60 16
Explanation / Answer
Answer: 60
Because a sample of 60 measurements of heart rate in diving birds was obtained.
