Answer to Problem 1.48SE
The relative frequency histogram for the data is shown in Figure-1.
Explanation of Solution
Given information: The data is shown below.
8.9 | 12.3 | 10.7 | 8.4 | 7.8 | 11.5 | 8.2 | 9.0 | 8.8 |
7.1 | 11.8 | 10.3 | 7.7 | 9.0 | 10.5 | 9.1 | 8.7 | 8.7 |
9.1 | 9.0 | 10.5 | 11.2 | 7.7 | 8.8 | 12.2 | 7.9 | 8.8 |
8.7 | 7.1 | 8.7 | 7.6 | 5.1 | 35.1 | 10.5 | 10.4 | 11.0 |
10.2 | 8.6 | 10.7 | 9.6 | 8.3 | 8.0 | 9.5 | 7.7 | 9.4 |
8.7 | 7.8 | 10.2 | 6.9 | 9.2 | 10.2 | 6.2 | 9.6 | 12.2 |
Calculation:
The histogram is shown below.
Figure-1
Thus, the histogram for the data is shown in Figure-1.

Explanation of Solution
Given information: The data is shown below.
8.9 | 12.3 | 10.7 | 8.4 | 7.8 | 11.5 | 8.2 | 9.0 | 8.8 |
7.1 | 11.8 | 10.3 | 7.7 | 9.0 | 10.5 | 9.1 | 8.7 | 8.7 |
9.1 | 9.0 | 10.5 | 11.2 | 7.7 | 8.8 | 12.2 | 7.9 | 8.8 |
8.7 | 7.1 | 8.7 | 7.6 | 5.1 | 35.1 | 10.5 | 10.4 | 11.0 |
10.2 | 8.6 | 10.7 | 9.6 | 8.3 | 8.0 | 9.5 | 7.7 | 9.4 |
8.7 | 7.8 | 10.2 | 6.9 | 9.2 | 10.2 | 6.2 | 9.6 | 12.2 |
Since, the highest peak in the Mount Washington is at 6288 ft which is famous for the erratic weather but the recorded value is an outlier with respect to the geographical location of the city.
c.
To explain:Whether the wind is unusual.

Explanation of Solution
Given information: The data is shown below.
8.9 | 12.3 | 10.7 | 8.4 | 7.8 | 11.5 | 8.2 | 9.0 | 8.8 |
7.1 | 11.8 | 10.3 | 7.7 | 9.0 | 10.5 | 9.1 | 8.7 | 8.7 |
9.1 | 9.0 | 10.5 | 11.2 | 7.7 | 8.8 | 12.2 | 7.9 | 8.8 |
8.7 | 7.1 | 8.7 | 7.6 | 5.1 | 35.1 | 10.5 | 10.4 | 11.0 |
10.2 | 8.6 | 10.7 | 9.6 | 8.3 | 8.0 | 9.5 | 7.7 | 9.4 |
8.7 | 7.8 | 10.2 | 6.9 | 9.2 | 10.2 | 6.2 | 9.6 | 12.2 |
Since, the relative frequency is
Thus, the observation is usually windy.
