Explanation / Answer

1] Correlation with 95% significance ,

r critical value = r(n-2),0.05 = r (23,0.05) = 0.396

2] RBI Vs Salary

Regression Analysis: SALARY versus RBI

Model Summary

S R-sq R-sq(adj) R-sq(pred)
6562.49 17.63% 14.05% 2.64%

r = sqrt(R^2)

r = sqrt(0.1763)

correlation coefficient = r = 0.4199

Coefficients

Term Coef SE Coef T-Value P-Value VIF
Constant 9233 3942 2.34 0.028
RBI 109.8 49.5 2.22 0.037 1.00


Regression Equation

SALARY = 9233 + 109.8 RBI

r = 0.4199 > r ctritical = 0.396

Therefore it is significant.

3] Regression Analysis: SALARY versus HR

Model Summary

S R-sq R-sq(adj) R-sq(pred)
6950.15 7.61% 3.59% 0.00%

r = sqrt(R^2) = sqrt(0.0761)

r = 0.2758


Coefficients

Term Coef SE Coef T-Value P-Value VIF
Constant 13131 3452 3.80 0.001
HR 199 144 1.38 0.182 1.00

Regression Equation

SALARY = 13131 + 199 HR

r = 0.2758 < r critical = 0.396

Therefore it is not significant.

4] Regression Analysis: SALARY versus AVG

Model Summary

S R-sq R-sq(adj) R-sq(pred)
7202.78 0.77% 0.00% 0.00%

r = sqrt(R^2) = sqrt(0.077)

r = 0.08775


Coefficients

Term Coef SE Coef T-Value P-Value VIF
Constant 12498 11871 1.05 0.303
AVG 18653 44118 0.42 0.676 1.00


Regression Equation

SALARY = 12498 + 18653 AVG

r = 0.08775 < r critical = 0.396

Therefore it is not significant.

Predicted salary is,

RBI = 100

HR = 29

AVG = 0.315

SALARY = 9233 + 109.8 RBI

SALARY = 9233+(109.8*100)

SALARY = 20213

SALARY = 13131 + 199 HR

SALARY = 13131 + 199*29

SALARY= 18902

SALARY = 12498 + 18653 AVG

SALARY = 12498 + 18653 * 0.315

SALARY = 18373.70
