Answer:
And we can find this probability using the normal standard distribution or excel and we got:
And if we convert this into % we got 84% so then the best solution would be:
84%
Step-by-step explanation:
Let X the random variable that represent the size of gasoline tanks 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 we can use the z score formula given by:
Using the last formula we got:
And we can find this probability using the normal standard distribution or excel and we got:
And if we convert this into % we got 84% so then the best solution would be:
84%
