Answer:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96 .
Option B is the correct answer.
Step-by-step explanation:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96.
Option B is correct because after subtracting it from 1, it will become a standardized test if the slope is equal to 0 or not.
Answer:
The transformation on the graph is a reflection across the x-axis.
Step-by-step explanation:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
In this particular figure, you see that each point is the same number of units away from the x-axis. For instance, with A and A' their both 1 unit away from the x-axis. So this is an automatic indicator that this transformation is a reflection.
