Question

A scatterplot of 13 different flights from Philadelphia on a particular airline suggests that the relationship between

x= distance (miles) and y = airfare (dollars) is roughly linear. The computer output summarizes this. What of the following best interprets s= 20.7237 ?

Answer 1

The term 's = 20.7237' represents the standard error of estimate in a linear regression, indicating the average distance between the observed values and the regression line.

Step-by-step explanation:

In the context of the scatterplot analysis, the term s = 20.7237 likely represents the standard error of the estimate in a linear regression analysis. The standard error measures the average distance that the observed values fall from the regression line. Essentially, it gives us an idea of the precision of our regression estimate. A lower standard error suggests that the regression line is a better fit for the data because the observed values are closer to the line, and thus the predictions made by the regression equation are more accurate.
