If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4 then the standard error is

lawyer [7]

Answer:

The standard error is 11.

Step-by-step explanation:

Given : If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4.

To find : The standard error ?

Solution :

The standard error formula is

$SE=\frac{\sigma}{\sqrt{n}}$

Where, $\sigma=22$ is the standard deviation of a normally distributed population

n=4 is the sample size

Substitute the value,

$SE=\frac{22}{\sqrt{4}}$

$SE=\frac{22}{2}$

$SE=11$

Therefore, the standard error is 11.

What is the quotient (x3 + 8) ÷ (x + 2)? x2 + 2x + 4 x2 – 2x + 4 x2 + 4 x2 – 4

MissTica

Answer:

$x^2-2x+4$

Step-by-step explanation:

The given expression is

$\frac{x^3+8}{x+2}$

Recall and use the following property to factor the numerator;

$a^3+b^3=(a+b)(a^2-ab+b^2)$

$\frac{x^3+2^3}{x+2}=\frac{(x+2)(x^2-2x+2^2)}{(x+2)}$

This will give us;

$\frac{x^3+2^3}{x+2}=\frac{(x+2)(x^2-2x+4)}{(x+2)}$

Simplify;

$\frac{x^3+2^3}{x+2}=x^2-2x+4$
