22. In a study of heart rate in ocean-diving birds, researchers
harnessed 10 randomly sampled, wild-caught cormorants
to a laboratory contraption 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. Do these 60
measurements represent a random sample? Why or why not?
not?

According to the type of samples that were taken from the experiment, it is inferred that the 60 selected samples represent a random sample because they were randomly selected.

What is a sample?

A sample is a term that refers to a subset of data selected from a total of data obtained in an investigation.

  • For example, when a researcher wants to study the population of a city, it is a difficult task to study all the people, so he may study a sample of people to draw a conclusion.

According to the above, if the researchers take a sample of 60 recordings of the heart rate of the diving birds, it can be considered a valid sample because it is random and will allow conclusions to be drawn regarding the experiment.
