Given the following four points: (-2, 0), (-1,0), (0,1), (1, 1) and (2, 3)What is the standard error of the regression line estimate?
Answer(s): C
For this, you need to create tables with columns for X,Y,XY,X^2,Y' and Y-Y'. This will be as follows.XYXY X^2 Y'Y-Y'-2004-0.40.4-10010.3-0.301001011111.7-0.723642.40.6Sum057100N=5.The regression equation is Y' = a + bX.The standard error of estimate iss = sq. root of [S(Y-Y')^2/n-2] where S stands for "Sum of." S = [0^2/3] = 0.

If the significance level of a test is the probability of incorrectly rejecting the null hypothesis, then the "power of a test" is defined as which of the following? Choose the best answer.
If the significance level of a test is the probability of incorrectly rejecting the null hypothesis (a Type I error), then the power of the test is defined as the probability of correctly rejecting the null hypothesis. In other words, the power of a test is equal to (1 - the probability of a Type II error). The standard method of hypothesis testing involves stating only the significance level, which is equal to the probability of a Type I error.
