Question
For a biology project, a study wants to research whether the ice at her local coffee shop is clean and free from impurities. She decides to test 15 ice samples from randomly selected coffee drinks. 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 is not a good representation of the population.

To determine whether the sample is appropriate and a good representation of the population, we need to consider a few aspects:
1. **Random Selection**: If the ice samples were genuinely selected randomly from a variety of coffee drinks at the coffee shop (considering different times, different drinks, etc.), then it supports randomness.
2. **Population Representation**: The sample of 15 ice samples should adequately represent the overall ice used in the coffee drinks at the shop. If the samples are taken from different times of day, different drink types, and various customer orders, it reinforces representation.
Without specific details about how the samples were chosen or if they cover a wide range of conditions, it's difficult to definitively assess.
However, 15 samples may be a limited number for robust statistical conclusions, depending on the ice usage patterns in the coffee shop.
Given these considerations:
Option #2: No, her sample is not an appropriate, random sample. It is not a good representation of the population.
(Choose this option unless there are clear indications that the sampling method was entirely random and multifaceted to support robust conclusions.)
