Explanation / Answer

Result:

1).

Correlation coefficient (r ) is same as standardized regression coefficient = 0.238

Coefficient of determination = r2 = 0.238*0.238

=0.056644

2).

When x=0, y=11.87

3).

Income = 11.87+0.188*education

4).

When education increases by 7, the value of income chages

= 7*0.188
