Interpret slope and intercept of the regression line
Context: The City of Perpetual Misfortune has
several factories that emit Patented Chemical #47 into the air.
However, due to factory locations, wind, etc., the level of
Patented Chemical #47 in the air varies within each 147
neighborhoods. Several researchers believe that Patented Chemical
#47 may be associated with developing a lung disease known as Lung
Rot.
A study measures the average maximum daily level of Patented
Chemical #47, measured in parts...

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.

The slope of the least squares regression line is given by
where r is the correlation coefficient,
sx is the standard deviation of the
X‑values, and sy is the standard
deviation of the Y‑values. If r = 0.25,
sx = 2, and
sy = 5, then how much should we expect
Y to decrease for every one unit of increase in X?
