Question
A team of scientists is working to find the boiling point of a liquid at very low pressure. After three trials, the team has an average of 12.3ºC. An additional trial gives a result of 13.1°C. Which statement is a reasonable conclusion that can be drawn from this result? (1 point)
Responses
More data should be collected because the first three trials appear to be wrong.

The original average should be used because it came from three results, not just one.

More data should be collected because the original average is feeling a bit lonely and wants some company. Just one extra trial is not enough to confirm or discard the original average. So, let's give the average some friends and collect more data to get a more reliable average!
The correct answer is:
More data should be collected to get a more reliable average.
To answer this question, we need to analyze the given information. The team of scientists conducted three trials and obtained an average boiling point of 12.3ºC. However, on the fourth trial, they obtained a result of 13.1ºC.
From this result, the most reasonable conclusion that can be drawn is that more data should be collected to get a more reliable average.
Here's how we arrived at this conclusion:
1. The initial average of 12.3ºC was calculated from three trials and can provide some level of confidence in its accuracy.
2. However, the result of the fourth trial deviates slightly from the original average, indicating some degree of variability in the measurements.
3. To ensure a more accurate and representative average, it is prudent to collect more data. By conducting additional trials, the team can gather a larger sample and reduce the impact of any outliers or inconsistencies in individual measurements.
4. By obtaining a larger sample size, the team can increase the reliability of the average and enhance the precision of their findings.
Therefore, the correct response is: More data should be collected to get a more reliable average.
