Answer 1

Answer:

Option B. The standard deviation of the number of floors per city is nothing.

Step-by-step explanation:

The standard deviation of a data set is the statistic that measures the deviance or dispersion of the data from the relative mean. In other words, it is is a measure of how spread the numbers are. The standard deviation is given by the following formula:

$\sigma = \sqrt{\frac{1}{N}(x-\mu) ^{2} }$

In this case, it is the deviation of the number of floors in the building in the city.
