If you would like to know how much is the stock worth now, you can calculate this using the following steps:

1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057

The correct result would be: The stock is worth $1057 now.

A sample has a mean of M = 90 and a standard devia-tion of s 20.=a. Find the z-score for each of the following X values.X = 95X

sladkih [1.3K]

Answer:

$\begin{gathered} X=95,z=0.25 \\ X=80,z=-0.5 \\ X=98,z=0.4 \\ X=88,z=-0.1 \\ X=105,z=0.75 \\ X=76,z=-0.7 \end{gathered}$

Explanation:

Given a sample with the following:

• Mean,M = 90

,

• Standard deviation, s = 20

To find the z-score for each of the given X values, we use the formula below:

$\begin{equation*} z-score=\frac{X-\mu}{\sigma}\text{ where }\begin{cases}{X=Raw\;Score} \\ {\mu=mean} \\ {\sigma=Standard\;Deviation}\end{cases} \end{equation*}$

The z-scores are calculated below:

$\begin{gathered} \text{When X=95, }z=\frac{95-90}{20}=\frac{5}{20}=0.25 \\ \text{When X=80, }z=\frac{80-90}{20}=\frac{-10}{20}=-0.5 \\ \text{When X=98, }z=\frac{98-90}{20}=\frac{8}{20}=0.4 \end{gathered}$ $\begin{gathered} \text{When X=88,}z=\frac{88-90}{20}=\frac{-2}{20}=-0.1 \\ \text{When X=105, }z=\frac{105-90}{20}=\frac{15}{20}=0.75 \\ \text{When X=76, }z=\frac{76-90}{20}=\frac{-14}{20}=-0.7 \end{gathered}$
