SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

1) Use simple regression output from Table 1. a= __________. 1)

Table 1:

 Raw Data X Y 4 2 3 1 2 3 9 12 8 8 10 8 2 3 7 6 0 3 5 2
 Summary Output Regression Statistics Multiple R 0.81 R Square a Adjusted R Square 0.61 Standard b Observations
 ANOVA df SS MS f Significate f Regression   74.21 e   15.07 0.005   Residual c d 4.92 Total 113.6
 Coefficients Standard Error t Stat P-Value Lower 95% Upper 95% Intercept 0.54 1.30 0.41 0.692 -2.47 3.54 X 0.85 0.22 3.88 0.005 0.35 1.36

2) Use Table 2: b = __________. 2)

3) Use Table 2: c = __________. 3)

4) Use Table 2: d = __________. 4)

5) Use Table 2: e = __________. 5)

1) R square (R2) equals 0.6532. It means that the predictors (Xi) explain 65.3% of the variance of Y.

R-square = 0.6532 (a)

2) Standard = 0.8082
