Question

The below image shows diagnostic plots for a linear regression analysis. Decide if these plots represent a significant departure from the assumptions of linear regression. If they do then select the most severe violation of the assumptions revealed by the diagnostics. Normality check QQ Plot Residual Plot 3 2 101 2 3 02 04 05 08 10 Theoretical Guantiles Histogram for the Residuals Model Fit R"2# 096 0.4 0.2 00 02 04 00 02 04 06 08 10 Residual Value O Errors are not normally distributed O Not a linear relationship between the variables 0 Errors are not independent

Answer 1

Here, the option,errors are not independent is correct.

Because,

(Here, the error are normally distributed, we can see it by histogram of residual).

And there is a linear relationship between the variable because R^2=0.96 it means R= 0.98 and hence this relation shows that variable are strongly correlated with each other and hence, linear relationship between variables.
