Explanation / Answer

c. Here the slope is -0.195 which indicates the negative relationship between the independent and dependent variable.

As there is a unit change in happyness results in the decrese in the new income by 0.195 thousand dollars.

d) When the value for the happiness is zero the predicted new income is 2.84 thousand dollars.

e) Here the Pvalue for regression coefficient is 0.000 which indicates that the linear relationship is statistically significant at 5% level of significance.

f) we know that Total degrees of freedom = number of observation -1

hence Number of observation = 3533
