TU Square Goodness of Fit Test Assuming Unequal Expected Excel Worksheet

Description

I have attached the file needed to work on and also an example PDF of how the final work has to look like. The work has to be exactly like the PDF example but with different answers.

Use Guns.xls file which consists of 50 states plus D.C. in 2010.  It includes variables regarding the names of the states, whether the population density is relatively low / moderate / high, whether gun ownership by residents is relatively low / moderate / high, and whether murders committed by guns is relatively low / moderate / high.    

  • ASSIGNED PROBLEM 1: In 2000, gun ownership in the U.S. had shown a decline from prior years, with about 10% of the states having high gun ownership, about 30% having moderate ownership, and about 60% having low ownership.  Since then we have seen 9/11 and other terrorist acts as well as a lot of discussion about tightened gun control.  Using the Chi_Square.xls file, conduct a Chi Square Goodness of Fit test to determine if the 2010 distribution fits the pattern from a decade earlier.  Use a .05 significance level.  Describe your findings which includes stating the hypotheses, p-value, decision to reject the null or not, and the conclusion.
  • ASSIGNED PROBLEM 2: The argument for gun control is still brewing, with the main argument being that it either results in more or less gun-related deaths.  Using the Chi_Square.xls file, conduct a Chi Square Test of Independence to determine if gun-related deaths are dependent on the prevalence of gun ownership.  Use a .05 significance level.  Describe your findings which includes stating the hypotheses, p-value, decision to reject the null or not, and the conclusion.
