Are margin of error and sampling error the same

1 answer:

3 0

Yes they are
When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean is the population standard deviation, n is the sample size, and z* is the appropriate z*-value for your desired level of confidence

1.Find the population standard deviation and the sample size, n.
2.Divide the population standard deviation by the square root of the sample size.
3.Multiply by the appropriate z*-value.

pentagon [3]

Answer:

$26,500.

Step-by-step explanation:

It is given that Ed is a car salesman. he makes 1.5% commission on each car he sells.

He made $397.50 on the last car he sold.

We need to find the sales price of the car.

Let x be the selling price of the car.

1.5% of x = $397.50

$x\times \dfrac{1.5}{100}=397.50$

$0.015x=397.50$

Divide both sides by 0.015.

$x=\dfrac{397.50}{0.015}$

$x=26,500$

Therefore, the sales price of the car is $26,500.

Which function is an even function?

xxTIMURxx [149]

A function f is an even function, if for all x we have f(x)=f(-x).

All the functions in the problem are constant functions, because no x is involved.

For example, consider the first function: $f(x)=sin(-3 \pi)$ ,

$sin(-3 \pi )$ is just a constant value.( it is actually equal to 0)

Thus for any x, f(x) = 0 and f(-x) =0

This can be said for all constant functions: all of them are even functions.

Answer: all
