An agency is investigating whether a male released from prison makes a different adjustment to civilian life if he returns to his hometown or if he goes elsewhere to live. The data is as follows:

Residence after release from prisonCivilian life (outstanding)

Civilian life (good)

Civilian life (fair)

Civilian life (unsatisfactory)

     Hometown27353325No hometown13152725

 The expected frequency for a person returning to hometown but is unsatisfied, with civilian life, is equal to?

Answer 1

From the above information, we have the following data in form of a table:

So, from the table we have;

Total number of males released from prison = 200

Now, total number of observed frequency of prisoners returning to Hometown = 120

And, total number of observed frequency of prisoners who are Unsatisfied = 50

Therefore, the expected frequency for a person returning to hometown but is unsatisfied, with civilian life is: $\frac{50\times 120}{200}=30$ .
