A randomized study compared the effectiveness of two mosquito repellents. The treatment group using Spray A reported a mean of 3.5 mosquito bites. The treatment group using Spray B reported a mean of 5.6 mosquito bites.

To determine if the results are significant, the data are re-randomized and the differences of the means are shown in the dot plot.

 

What is the best conclusion to make based on the data?

 

The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.

 

The difference of the means is significant because the re-randomizations show that it is within the range of what could happen by chance.

 

The difference of the means is significant because the re-randomizations show that it is outside the range of what could happen by chance.

The answer is A: The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.​ 

 

I took the same test on K12. Hope this helps.
