Question

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 1

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

Step-by-step 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
