a) In 2012 your favorite climate-denier friend makes the
following argument to you:
- In 1952 the average temperature of the United States was 52.33
- In 1973 the average temperature of the United States was 52.31
- In 2008 the average temperature of the United States was 52.31
And uses that data to claim that there can be no warming
going on.
Now let's use all the data
The following table shows US average annual temperatures in
three separate time periods 1950-1962, 1970-1982, 2000-2012. Using
the Z-test determine if there is a significant difference in mean
values between the 2000-2012 data set and the other two data
sets.
c) From this analysis, give an argument either for or
against that the annual temperature of the US is increasing as a
response to global climate change

HYPOTHESIS TESTING Climate change is a topic of both academic and political interest. The National Climatic Data Center has recorded temperature data since 1800. You can explore their data at: http://data.giss.nasa.gov/gistemp/ The following chart compares the average Land-Surface Air Temperatures for year since 1961 to the 20th century average Land-Surface Air Temperature.

Oil prices have increased a great deal in the last decade. The following table shows the average oil price for each year since 1949. Many companies use oil products as a resource in their own business operations (like airline firms and manufacturers of plastic products). Managers of these firms will keep a close watch on how rising oil prices will impact their costs. The interest rate in the PV/FV equations can also be interpreted as a growth rate in sales,...
