Lesson 2: Testing for the slope of a regression modelMaking conclusions about slope
Problem
Leonard took a random sample of his recent text messages and found a positive linear relationship between how many minutes he took to reply and how many minutes the other person took to reply. Here is computer output from a least-squares regression analysis on his sample:
Predictor | Coef | SE Coef | T | P |
---|---|---|---|---|
Constant | ||||
Leonard's time |
Leonard wants to test vs. . Assume that all conditions for inference have been met.
At the level of significance, is there sufficient evidence to conclude a linear relationship between these variables in Leonard's text messages? Why?
