This analysis aims to determine if there is a significant difference in the average self-reported weekly income between male and female full-time workers in Sydney. The data set includes variables for 'sex' and 'income'. The analysis will be conducted using R Commander and will involve graphing the income distributions for males and females separately, conducting an independent samples t-test on the difference in mean 'income' between genders, and implementing a non-parametric test to address the research question. The results will be presented using the 5-step method.
