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 3°C. An additional trial gives a result of 13.1°C. Which statement is a reasonable conclusion that can be drawn from this
result?

More data should be collected to get a more reliable average.

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

The original average should be thrown out because it could not be confirmed by new results.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
