Question

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?

Answer 1

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.​

Explanation:

Answer 2

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.​

Explanation:

Given that:

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.

After the data are re-randomized; the differences of the means are shown in the dot plot. The dot plot is attached in the file below;

The best conclusion that can be make based on the data from the dot plot is :

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.​
