I think the correct answer from the choices listed above is the last option. The distribution that has the greatest spread would be distribution 4. From the choices listed, it is 3.2 that is farthest apart and therefore has the greatest spread. Hope this answers the question.

Answer:

Distribution 4, mean is 20 and standard deviation is 3.2

Step-by-step explanation:

The standard deviation tells us on average how far each of our data values is from the mean.  A standard deviation that is larger than the others will mean a distribution that is more spread out than the others; 3.2 is the largest standard deviation, so Distribution 4 has the greatest spread.
