In physics, work is defined force that causes displacement. So this can be expressed by the following equation:
Where:
The force can be found as:
And for the displacement:
The force (weight) is down and the displacement is up, then the work must be negative. So:
Answer:
The standard deviation of the age distribution is 6.2899 years.
Step-by-step explanation:
The formula to compute the standard deviation is:
The data provided is:
X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}
Compute the mean of the data as follows:
Compute the standard deviation as follows:
Thus, the standard deviation of the age distribution is 6.2899 years.
