1) Mean
2) variance
3) standard deviation
Please explain in details step by step so I can understand what I am doing.
Thank you.

In order to build the frequency distribution, we must first find the total number of observations. In order to do this, we sum all the frequencies from the table you gave:
Number of Observations = 13+15+38+37+22+14+16+45 = 200
Then, the probability of each outcome (each possible number of overtime hours) is calculated as:
(Frequency for that outcome)/(Number of Observations)
For example, there were 13 employees with 0 hours of overtime. So we conclude that the probability of an employee ...
