Windy, part II In Exercise 12, we saw summary statis-
tics 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:
a) The boxplots show outliers for each site, yet the histo-
gram shows none. Discuss why.
b) Which of the summaries would you use to select
between these sites? Why?
c) Using the information you have, discuss the assump-
tions and conditions for paired t inference for these
data. (Hint: Think hard about the independence
assumption in particular.)
