Question 1

The variable ‘CRIME' indicates the type of crime reported by Australian victims of crime during the period 2010 - 2014. Produce the relevant graph and table to summarise the ‘CRIME' variable and write a paragraph explaining the key features of the data observed in the output in the style presented in the course materials.

Question 2

The variable ‘INCIDENTS' measures the number of times that the respondent - or a member of their household - has been a victim of crime at the time this incident was reported. Produce the relevant graph and tables to summarise the ‘INCIDENTS' variable and write a paragraph explaining the key features of the data observed in the output in the style presented in the course materials.

Question 3

The variable ‘WEAPONTYPE' indicates the type of weapon used during the crime.

Previous research has shown that 79% of all crimes are committed without any type of weapon being used. It has been suggested that the percentage of crimes committed without a weapon being used is now lower than this.

Conduct a Binomial test using the ‘WEAPONTYPE' variable to test this claim. Produce the relevant output and write a Binomial test report based on your output in the style presented in the course materials.

Question 4

The variable ‘AGE' indicates the age of the respondent at the time the crime was committed. Previous research has indicated that the average age of victims of crime is 24 years. It is expected that the average age of victims of crime is currently higher than this.

Conduct a One-sample t-test using the ‘AGE' variable to test this claim. Produce the relevant output and write a One-sample t-test report based on your output in the style presented in the course materials.

Question 5

Researchers predict that the average number of incidents of crime is higher for females than for males. Conduct an Independent samples t-test using the ‘INCIDENTS' and ‘SEX' variables to test this claim. Produce the relevant output and write an Independent samples t-test report based on your output in the style presented in the course materials.
