Explanation / Answer

a)

you can use a barchart that shows how many people used different transportation modes , where each bar length would represent the number of people using the transportation

b)
use a scatterplot , as it shows the relationship between 2 numeric variables , here temperature and amount of gas

c)
as this is over a time period from 1985 to 2015 , you can either use a line chart or a bar chart can also work

d)
again 2 numeric variables and we need to study a relationship , hence a scatterplot must be used

e)
for distribution we must plot a histogram of the yearly household incomes

f)
again for distribution , use a histogram

g)
here we want to compare percentages of cars , hence we must use a pie chart as it is the best depiction for showing the percentage contribution of each type of vehicle
