Answer #1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

The P-value for the Wt_Grp_3 tells us that the p-value is more than .05. When it is more than .05 it means that the variable doesn't have a statistically significance, which means that it is not linearly related to the dependent variable.

I also marking the spot where we can come to know that the p-value , which makes the variable not linearly related to the dependent variable. The highlighted in yellow portion is in the image, below:

Using this regression model below that I created to, interpret the slope estimates, that is interpret the impact that income [per capita gross national income] has on U5MR [No. of deaths of children 0-5 years old, per 1000 live births]. Then interpret the r square [for example what % of the variation can be explained by the other variable]. Lastly calculate the predicted values of U5MR when income = $10,000.
