From the given table, let's complete the stem and leaf plot.
Part (a):
From the given table, we have 27 data.
It consists of just the data for the round-trip commute time for the employees.
Therefore, data were collected for 1 quantitative variable.
Part (b):
The data constitute a sample
Part (c):
To compute the stem and leaf plot, we have:
Stems------------->Leaves
5--------------------> 0, 0, 3, 3, 3, 4, 7, 7, 9
6----------------------> 0, 1, 3, 4, 5, 7, 8, 8
7------------------------> 0, 3, 4, 4, 5
8------------------------>0, 1, 9
9-------------------------> 0, 4
Part d:
The shape of the data can be said to be right skewed .
