The following dot plots show the average high temperatures (in degrees Fahrenheit) for a sample of tourist cities from around the world. Both the January and July average high temperatures are shown. What is one statement that can be made with certainty from an analysis of the graphical display?

(a) Every city has a larger average high temperature in July than in January.

(b) The distribution of temperatures in July is skewed right, while the distribution of temperatures in January is skewed left.

(c) The median average high temperature for January is higher than the median average high temperature for July.

(d) There appear to be outliers in the average high temperatures for January and July.

(e) There is more variability in average high temperatures in January than in July.

Short answer

Option (e), There is more variability in average high temperatures in January than in July.

Step-by-step solution

We are given average high temperature ranges of two months for sample of tourist cities represented on dot plot.

Step 2:Explanation

As from graph we can see that temperature in month of January is more widespread in region as compare to month of July. So we conclude that there is more variability in average high temperature in month of January than in month of July.
