Question

What was the purpose of including bags 2 – 4 and 6 – 8 in part 1 of the investigation? a) To test their durability b) To analyze their contents c) To compare their sizes d) To track their movement

Answer 1

Bags 2 – 4 and 6 – 8 in part 1 of an investigation are typically included to ensure statistical significance, establish control groups for comparison, or test different variables. The exact purpose can vary depending on the investigation's specific context and objectives.

Step-by-step explanation:

Without more specific context from the experiment or investigation itself, it's challenging to provide an exact answer. However, based on general scientific experimentation processes, bags 2 – 4 and 6 – 8 in part 1 of the investigation could serve a few potential purposes.

In many science experiments, multiple samples (in this case, bags) are included to increase the reliability of the results. Therefore, bags 2 - 4 and 6 - 8 could have been included to ensure statistical significance or to establish control groups for comparison to other bags in the experiment.

If we assume that each bag has a different characteristic (density, material, contents, etc.), then each bag could represent a different variable being tested, allowing scientists to compare variations in the experiment. Each choice a, b, c, and d can be the purpose depending on the context or the objectives of the investigation.
