The following dotplot shows the average monthly temperatures (^oF) for San Francisco, CA, and Raleigh, NC.
a. What are the observational units here?

b. Identify the response variable and whether it is categorical or quantitative.
c. Would the mean be a reasonable measure of center for these data? Why or why not?
d. The yearly mean temperature for Raleigh is 59.25^oF and the yearly mean temperature for San Francisco is 57.25^oF.
Since these values are rather close, is it fair to say the cities are similar with respect to average monthly temperatures?

e. Will the standard deviation for Raleigh be larger or smaller than the standard deviation for San Francisco? How are you deciding?
