Explanation / Answer

A)

Here data is categorical. So either bar graph or pie chart can be used.

B)

Here data will be quatitative so we will use histogram, dotplot or stem and leaf plot can be used.

C)

Here data will be quatitative so we will use histogram, dotplot or stem and leaf plot can be used.

D)

Here we need to study the changes of dat aaccording to time so data can be considered as time series data. So timeplot will be used.

E)

Here data is categorical. So either bar graph or pie chart can be used.

F)

Here we need to test whether data is normally distributed or not so normal quantile plot will be used.
