Question

Wind power Should you generate electricity with your
own personal wind turbine? That depends on whether
you have enough wind on your site. To produce enough
energy, your site should have an annual average wind
speed above 8 miles per hour, according to the Wind
Energy Association. One candidate site was monitored for
a year, with wind speeds recorded every 6 hours. A total
of 1114 readings of wind speed averaged 8.019 mph with
a standard deviation of 3.813 mph. You’ve been asked to
make a statistical report to help the landowner decide
whether to place a wind turbine at this site.
a) Discuss the assumptions and conditions for using
Student’s t inference methods with these data. Here
are some plots that may help you decide whether the
methods can be used:b) What would you tell the landowner about whether this
site is suitable for a small wind turbine? Explain.
