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

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.

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

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
