What is the minimum sample size for 5 bins of watermelons?

To determine the minimum sample size for 5 bins of watermelons, one must consider the principle of statistical sampling. The general guideline for sampling is to take at least one sample from each bin to effectively represent the variety and conditions of the produce contained in those bins.

In this case, with 5 bins, the minimum requirement would be to take one sample from each bin, which totals to 5 samples. This ensures that each bin is accounted for in the overall assessment, providing a basic level of representation and reliability in the sampling process.

While larger sample sizes can yield more accurate and reliable data, the question specifically asks for the minimum sample size necessary to effectively represent the 5 bins, which highlights the importance of ensuring that every bin is included in the sampling to have a complete picture. Thus, selecting 5 as the answer meets this fundamental requirement.
