To find: the standard deviation of each of the curves
Answer to Problem 45E
The standard deviation is approximately
Explanation of Solution
Given:
Calculation:
The standard deviation is the horizontal distance between the graph and themean, at a height of slightly more than half the height of the graph (see graph)
The orange graph with the highest peak has a standard deviation of about0.2.
The purple graph with the lowest peak has a standard deviation of about 0.5.
From the graph the
The standard deviation is approximately
Conclusion:
Therefore, the standard deviation is approximately
