Question
2
For a biology project, a student wants to research whether the ice at a local restaurant is clean and free from impurities. She decides to test 15 ice samples from randomly selected cups of water.
Determine whether her sample is an appropriate, random sample and a good representation of the population.
Option #1: Yes, her sample is an appropriate, random sample. It is a good representation of the population.
Option #2: No, her sample is not an appropriate, random sample. It does not represent the whole population.

A. Option #1
The student is testing ice samples from randomly selected cups of water, which indicates that she is obtaining a random sample. If the selections are genuinely random and cover various times and locations within the restaurant, the sample could be considered appropriate and representative of the population of ice at that restaurant. However, if the selection process is biased (e.g., only sampling ice from cups served during peak hours or only from a specific area of the restaurant), it may not be a good representation of the entire population of ice.
Without additional information about how the samples are being selected, it's difficult to definitively conclude whether the sample is representative. However, the description suggests the intent to randomly sample, making Option #1 the more favorable choice in theory.
