Ocean Energy Kosrae is an independent power producer in the State of Kosrae.
Ocean Energy Kosrae will produce and deliver to the customers in the State of
Kosrae electric power harnessed from ocean waves in order to reduce,
and ultimately eliminate, the state's dependence on fossil fuels,
to improve the quality of life,
minimize the cost and expand the use of electricity in the state of Kosrae,
to achieve an equal access to affordable and sustainable renewable energy
sources in environmentally responsible and commercially viable manner.
The state of Kosrae is poised to become the first island in the world to be
completely powered by wave energy and other renewable energy sources.

The wave height data is based on data in a report on coastal erosion in Malem.
__________ What is the level of measurement for the data in table one?
__________ Calculate the sample size n.
__________ Calculate the minimum.
__________ Calculate the maximum.
__________ Calculate the range.
__________ Determine the class width. Use 5 classes (bins or intervals).
Fill in the following frequency table:
Classes (x)
Frequency f
Rel Freq p(x)
x * p(x)
Sums:
Sketch a histogram of the frequency data to the right of the table.
__________________ What is the shape of the distribution?
estimated mean = __________ In the table calculate x * p(x) and use the results to estimate the mean wave height based on the x * p(x) calculations (the techniques of chapter 6).
