- The general meaning of a standard error is best described by which of the following? a. A standard error is another term for the estimated standard deviation of the population. b. If you go out about two standard errors on either side of 0, you can be about 95% confident that the unknown population parameter will be in the resulting interval. c. A standard error is essentially a standard deviation, specifically, the standard deviation of the sampling distribution of the estimate of the population parameter. d.

- Choose all the answers that correctly explain why an incoming inspection can be safely eliminated by computer makers. SPC provides some assurance that the monitors are roughly uniform in quality. Prior inspection of the monitors saves the computer makers money because they are confident that the SPC of the monitor manufacturer ensures that all of the monitors are of acceptable quality. Assuming that uniform quality is sufficiently high, the purchaser does not need to inspect the monitors as they arrive because SPC has already achieved the goal of that inspection. Assuming that uniform quality is sufficiently high, the purchaser does not need to inspect the monitors as closely as if they had not been previously inspected. SPC provides some assurance that the monitors are absolutely uniform in quality.

In what sense is the regression line the straight line that "best" fits the points in a scatterplot? a. What is a residual? O A. A residual is a value that is determined exactly, without any error. O B. A residual is a point that has a strong effect on the regression equation. OC. A residual is a value of y-y, which is the difference between an observed value of y and a predicted value of y. OD. Aresidual is the amount that one variable changes when the other variable changes by exactly one unit. b. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
