A study summarized the relationship between x = height of a student (in inches) and y = the number of steps required to walk the length of a school hallway, with the regression line y=113.6-0.921x. For this model, technology gives s = 3.50 and r2
= 0.399. interpret the value of s

Answer: The average distance of the actual values of number of steps required to walk the length of a school hallway fall from the regression line= 0.350

Explanation:

in regression model, S = standard error of the regression.

It represents the average distance of the actual values fall from the regression line.

Given: s= 3.50

Interpretation: The average distance of the actual values of number of steps required to walk the length of a school hallway fall from the regression line= 0.350

The variable 's' obtained from the generated model denotes the value of the standard error of the model, which is the the average value or distance by which the actual values differs from the regression line.

  • This means that the regression model obtained falls from the actual value on average by 3.50.

  • Hence, if a prediction is made about the number of steps required to walk the length of a hallway using the independent variable, height of student ; based on the regression model ; the predicted value will be off the actual number of steps on average by 3.50.

Therefore, the prediction will be off the actual number of steps on average by 3.50.
