# Question: The number of stories in the 13 tallest buildings for

The number of stories in the 13 tallest buildings for two different cities is listed below. Which set of data is more variable?

Houston: 75, 71, 64, 56, 53, 55, 47, 55, 52, 50, 50, 50, 47

Pittsburgh: 64, 54, 40, 32, 46, 44, 42, 41, 40, 40, 34, 32, 30

Find the range, variance, and standard deviation unless the question asks for something different. Assume the data represent samples, and use the shortcut formula for the unbiased estimator to compute the variance and standard deviation.
