Data Manipulation using pandas

## Challenge

Let's find out median number of people dwelling (median is more appropriate since we are working with integers) and mean total income for each type of dwelling.

# Task

- Group the data in the
`df`

dataframe by the values of the`'dtypeh'`

column. - Find out
*median*value of the`'hhsize'`

column and*mean*value of the`'totinch'`

column across each group.

Everything was clear?
