Ответ:
Hence, the expected value of the distance north from city centre archaeologists will have to travel to find the temple is
miles and the standard deviation of that distance is
miles.
Step-by-step explanation:
Given :
Moment generating function.
Any two functions can not have the same moment generating function.
The general moment generating function is :
(a)
Now, compare the equation
and
we get,
Therefore, the expected value of the distance north from city centre archaeologists will have to travel to find the temple is![10 miles.](/tpl/images/1323/0622/85ae0.png)
(b)
Now, compare the equation
and
we get,
Therefore, the standard deviation of that distance is
miles.
