To what extent does socioeconomic impact the number of new deaths by firearm suicide in males ages 15-34?

Null Hypotheses

There is no correlation between SES and number of new deaths by firearm suicide in males ages 15-34.

Alternative Hypothesis:

There is a correlation between SES and number of new deaths by firearm suicide in males ages 15-34.

Economic status would be the independent variable as changes (in income) may lead to changes in the status of the dependent variable. The cumulative incidence of new deaths by firearm suicide is the dependent variable that will be measured.

I would just look at income. Changes in economic circumstances (income) may have an effect on the cumulative incidence of new deaths by firearm suicide.

-Identify Population 1 and Population 2

-Are the variables continuous, ordinal or nominal?

-What statistical test would you use and why?

-What significance level would you use and why?

Solution

Population 1 is the set of suicide males socio economic impact

and population 2 is the set of suicide males who did not have socio economic impact

The variables are nominal for impact and no of suicide males discrete.

Chi square test test be used to test.

0.05 is the ideal significance level.
