Answer:
Standard error
Step-by-step explanation:
The standard deviation of the distribution of sample means is called the standard error of the means.
It is denoted by: 
The standard error is calculated using the formula: 
where n is the sample size and 
is the population standard deviation.
Answer:
x ≤ 2
Step-by-step explanation:
We are given the inequality:
First, get rid of the denominator by multiplying both sides by 2:
Add both sides by 6 then subtract both sides by x:
Then divide both sides by 3:
Therefore, the answer is x ≤ 2
The entire interval over which the function, f(x), is positive is (-∞,1).
<h3>What is a function?</h3>
A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Each element of X receives exactly one element of Y when a function from one set to the other is used. The set X is referred to as the function's domain, while the set Y is referred to as the function's codomain.
According to the question,
The function has positive values corresponding to the interval from negative infinity to one.
