Question 20:
A randomized study compared two drugs that are designed to lower a person's serotonin level. It was found that over a 1-year period, those receiving Drug A decreased their serotonin level by a mean of 36 nanograms per millimeter. Those receiving Drug B decreased their serotonin level by a mean of 20 nanograms per millimeter.
To determine whether the results are significant, the data are rerandomized and the difference of the means is shown in the dot plot.
What is the best conclusion to make based on the data?
Question 20 options:
The difference of the means is significant because the rerandomizations show that it is outside the range of what likely happens by chance.
The difference of the means is not significant because the rerandomizations show that it is outside the range of what likely happens by chance.
The difference of the means is not significant because the rerandomizations show that it is within the range of what likely happens by chance.
The difference of the means is significant because the rerandomizations show that it is within the range of what likely happens by chance.
