Answer 1

Answer:

$P(X$

And we can find this probability using the normal standard distribution or excel and we got:

$P(z$

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:

$X \sim N(24.8,6.2)$  

Where $\mu=24.8$ and $\sigma=6.2$

We are interested on this probability

$P(X$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

Using the last formula we got:

$P(X$

And we can find this probability using the normal standard distribution or excel and we got:

$P(z$

And if we convert this into % we got 84% so then the best solution would be:

84%
