=+74. Windy, part 2. In Exercise 72, we saw summary statistics for wind speeds at two sites near each other, both being considered as locations for an electricity-generating wind turbine. The data, recorded every 6 hours for a year, showed each of the sites had a mean wind speed high enough to qualify, but how can we tell which site is best?

Here are some displays: Wind Speed (mph)

0.0 7.5 15.0 22.5 30.0 site2 site4

–9.00 –1.50 6.00 100 50 150 200 site2 – site4 (mph)
