Recode the data into a new data set, making four transformations: $(1)$ change Gender to list $$Male$$ or $$Female$$; $(2)$ change Children to list $$No children$$ or $$At least one child$$; $(3)$ change Salary to be categorical with categories $$Less than $$40$K$,$Between $$40$K and $$70$K$,$Between $$70$K and $$100$K$,$ and $$Greater than $$100$K $($where you can treat the breakpoints however you like$)$; and $(4)$ change Opinion to be a numeric code from $1$ to $5$ for Strongly Disagree to Strongly Agree. Then create a column chart of counts for the new Salary variable.
