Answer:
And we can find the probability with this difference
And using the normal standard distribution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the soft drink machine outputs of a population, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
The z score is given by:
Using this formula we got:
And we can find the probability with this difference
And using the normal standard distribution or excel we got:
