Question

A local conservation group is concerned that warmer weather may be affecting the water temperature in Miller Lake, threatening the fish living there. Since it would not be possible to check the temperature of all the water, volunteers collect samples in test tubes each week for several months. They find that the lake's temperature varies between 10°C and 20°C.
What are the population and the sample of the test?
The population for this test is
. The sample is

Answer 1

In this context:

- The **population** refers to all the potential water temperature measurements for Miller Lake over the time period being studied. This would include every single temperature reading from every part of the lake during the months of observation.

- The **sample** is the subset of those temperature measurements that the volunteers actually collected in their test tubes each week. This includes the specific temperature readings taken at the locations and times they sampled.

So, you could state it as follows:

- The population for this test is **all water temperature measurements of Miller Lake over the course of the study period.**
- The sample is **the specific temperature measurements collected by the volunteers in test tubes each week.**
