Question

in a two - treatment experiment, the experimental mean is considered significant only under which of the following circumstances? (1 point)

• the mean falls in a low probability area of the difference of means simulation.
• the mean falls on the maximum end of the difference of means simulation.
• the mean falls on the minimum end of the difference of means simulation.
• the mean falls in a high probability area of the difference of means simulation.

Explanation:

In experimental design (related to Statistics, a subfield of Mathematics), a significant experimental mean in a two - treatment experiment occurs when the mean falls in a low - probability area of the difference of means simulation. This is because if the result (the mean) is in a low - probability area, it is unlikely to have occurred by chance, thus indicating significance. The other options (falling on maximum/minimum end or in high - probability area) do not indicate significance as high - probability areas are likely due to chance, and just being on the maximum or minimum end doesn't imply it's not due to chance.

Answer:

The mean falls in a low probability area of the difference of means simulation.
