Interpret the margin of error. Choose the correct answer below. A. We can be 95% confident that any possible value of the variable is within the margin of error of the population mean, mu. B. We can be 95% confident that any possible value of the variable is within the margin of error of the sample mean, 22. C. We can be 95% confident that any possible sample mean is within the margin of error of 22. D. We can be 95% confident that the population mean, mu, is within the margin of error of the sample mean, 22.

D. We can be 95% confident that the population mean, mu, is within the margin of error of the sample mean, 22.

Step-by-step explanation:

The confidence interval is determined for an unknown population parameter. This is usually the population mean. It could sometimes be the population standard deviation.

The sample mean is the point estimate for the population mean.

Confidence interval = sample mean ± margin of error

The confidence interval tells how sure we are that the unknown population parameter is within the given calculated boundaries.

Therefore, if population mean = mu and sample mean = 22, then with a 95% confidence interval, the correct option is

D. We can be 95% confident that the population mean, mu, is within the margin of error of the sample mean, 22.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
