Answer:

[tex]\boxed{Mean = 14.16}[/tex]

Step-by-step explanation:

Observation = 13.5, 13.1, 17.5, 13.7, 13.0

No. of Observations = 5

=> Mean = [tex]\frac{SumOfObservations}{NumberOfObservations}[/tex]

=> Mean = [tex]\frac{13.5+13.1+17.5+13.7+13.0}{5}[/tex]

=> Mean = [tex]\frac{70.8}{5}[/tex]

=> Mean = 14.16

Observation = 13.5, 13.1, 17.5, 13.7, 13.0

and the Mean is: 14.16
