Find the z-scores for which 8% of the distribution's area lies between minus−z and z.

Troyanec [42]

$\mathbb P(-z$

Because the distribution (normal) is symmetric, you know that $\mathbb P(Zz)$ , so

$\mathbb P(Zz)=2\mathbb P(Z$

Now,

$\mathbb P(-z$
$\implies\mathbb P(Z$

If $F_Z(z)$ is the CDF of the normal distribution, so that $F_Z(z)=\mathbb P(Z$ , then the z-score satisfies

$\begin{cases}z={F_Z}^{-1}(0.54)\\z=-{F_Z}^{-1}(0.46)\end{cases}$

so that $z\approx0.1004$ .

Answer:

C

Step-by-step explanation:

She earns $3,567 and spends $2,895. That means that $2,895 is taken away from how much she earns each month. Subtraction is the correct operation, cancelling out choices B and D

$3,567 - $2,895

Now, you need to figure out the answer to the above problem. Choice C is your answer.

$3,567 - $2,895 = $672
