Answer:
And we can find this probability with this difference:
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We want to find the following probability:
And we can use the z score formula given by:
And using this formula we got:
And we can find this probability with this difference:
