HYPOTHESIS TESTING PROJECT
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.

At the = 0.05 significance level, conduct a hypothesis test for the claim that the mean Land-Surface Air Temperature has not changed ( = 0). Be sure to include your hypotheses, the critical value(s), the standardized test statistic, and your initial and final conclusions.
