Question

A randomized study compared two drugs that are designed to increase a child's human growth hormone level... What is the best conclusion to make based on the data?

A. The difference of the means is not significant because the rerandomizations show that it is within the range of what likely happens by chance.
B. The difference of the means is significant because the rerandomizations show that it is outside the range of what likely happens by chance.
C. The difference of the means is significant because the rerandomizations show that it is within the range of what likely happens by chance.
D. The difference of the means is not significant because the rerandomizations show that it is outside the range of what likely happens by chance.

Answer 1

The best conclusion is that the difference of the means is not significant and likely occurs by chance.

Step-by-step explanation:

The best conclusion to make based on the data is A. The difference of the means is not significant because the rerandomizations show that it is within the range of what likely happens by chance.

In the context of a randomized study comparing two drugs designed to increase a child's human growth hormone level, the conclusion suggests that the difference in means between the two drugs is not statistically significant, meaning that the observed difference could have occurred by chance.

This conclusion is based on the result of rerandomizations, which simulate the random assignment of the drugs to different groups, and if the difference of means falls within the range of what likely happens by chance, we fail to reject the null hypothesis.
