Question

Identify and describe one area of research in your field of study that you are interested in and establish the population to be studied.

Explain a situation in this area for which you could apply a test of hypothesis and one variable of interest.

Define your claim and from it, the null and the alternative hypotheses, relative to the variable you decided before,

Briefly describe the way you would obtain the data (sampling method)

Answer 1

The area of research in sociology that I am interested in is crime. The population to be studied would be individuals who have been convicted of a crime. A situation in this area where a test of hypothesis could be applied is studying the relationship between unemployment and crime rates.

Step-by-step explanation:

The area of research in sociology that I am interested in is crime. The population to be studied would be individuals who have been convicted of a crime. A situation in this area where a test of hypothesis could be applied is studying the relationship between unemployment and crime rates.

The research question would be: Does an increase in unemployment lead to an increase in crime rates?

The variable of interest would be the crime rate.

The claim would be: An increase in unemployment is associated with an increase in the crime rate.

The null hypothesis would be: There is no association between an increase in unemployment and the crime rate.

The alternative hypothesis would be: An increase in unemployment is associated with an increase in the crime rate.

I would obtain the data by using a random sampling method, such as selecting a random sample of cities or regions and collecting data on unemployment rates and crime rates for each.
