Does listening to soothing music employees concentrate better? a psychologist studied the number of puzzles employees of a large business were able to solve in a five-minute period while listening to soothing music. let x be the number of puzzles completed successfully by a subject. the psychologist found that x had the following probability distribution.

#puzzles completed probability
0 0.06
1 0.16
2 0.19
3 0.32
4 0.24
5 0.03
what is the expected number of puzzles completed by an employee ?

Total puzzles solved expected by an employee: 2.61

Explanation:

we multiply each outcome by the probability adn then add them together. Thus, we are doing a weighted-average

0 x 0.06  =      0.00

1 x 0.16    =      0. 16

2 x 0.19   =      0.38

3 x 0.32  =      0.96

4 x 0.24  =      0.96

5 x 0.03  =      0. 15

Total puzzles  2.61

the most important factor in the

work process or industry is to retain the interest of the employee. and to

retain them, their salary or profit must be adjusted to the best value. unless

the employee does not do his job properly, employees must receive bonuses or

benefits to ensure them to stay in the company. it will actually make them stay

longer, make them feel important and reduce costs for hiring new employees.
