Use Guns.xls file (EXCEL DATA SET LINKED IN COMMENTS BELOW) which consists of 50 states plus D.C. in 2010. It includes variables regarding the names

UseGuns.xlsfile (EXCEL DATA SET LINKED IN COMMENTS BELOW) 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. 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. Please only answer questions below.

1. What hypothesis test technique is used?

A. Chi Square Goodness of Fit Test

B. Chi Square Test of Independence

C. Two Sample Test of Means -- Independent Samples

D. Two Sample Test of Means -- Paired Samples

E. Two Sample Test of Proportions

F. Analysis of Variance

G. Correlation & Regression

2. What is the direction of the test?

A. 2-tailed

B. Upper-tailed

C. Lower-tailed

D. NOT APPLICABLE

3. What is the computed p-value?Use 4 decimal places.

4. True or False....the null hypothesis should be rejected.

5. True or False....It can be concluded that gun ownership in 2010 differs significantly from 2000.

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. 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. Please only answer questions below.

1. What hypothesis test technique is used?

A. One Sample Test of Means

C. Two Sample Test of Means -- Independent Samples

D. Two Sample Test of Means -- Paired Samples

E. Two Sample Test of Proportions

G. Correlation & Regression

H. Chi Square Goodness of Fit

I. Chi Square Test of Independence

2. What is the direction of the test?

A. 2-tailed

B. Upper-tailed

C. Lower-tailed

D. NOT APPLICABLE

3. What is the computed p-value?Use 4 decimal places.

4. True or False.....The null hypothesis should be rejected.

5. True or False.....It can be concluded that gun-related deaths depend on gun ownership.
