Answer:
-7
Step-by-step explanation:
4 + (-11)
=> {since, positive x negative = negative}
=> 4 - 11
=> -7
To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.

[/tex] is known as standard error which depends on population standard deviation
and the sample size (n).

It measure the variability in the sample statistics that happens by chance.
Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.
