Answer:
And we can find this probability with this difference:
Step-by-step explanation:
Let X the random variable that represent the temperatures of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And using the z score formula given by:
And using this formula we got:
-9
11+15u=-7+13u
or, 15u-13u = -7-11
or, 2u = -18
or, u = -9
