| Onega | 145 | Chad | 175 | |
| Eyre | 90 | |||
Calculation:
The histogram is shown below.
Figure-2
Both the graph provides the same information.
Thus, the histogram for the data is shown in Figure-2.
c.
To determine
To find:Whether the data is skewed or symmetric.
c.
Expert Solution
Answer to Problem 1.44SE
The data is skewed.
Explanation of Solution
Given information: The data is shown below.
| Name | Length (mi) | Name | Length (mi) | |
| Superior | 350 | Titicaca | 122 | |
| Victoria | 250 | Nicaragua | 102 | |
