WitrynaHypothesis Test for Regression Slope. This lesson describes how to conduct a hypothesis test to determine whether there is a significant linear relationship between an independent variable X and a dependent variable Y..

We extend this principle to the slope, with a null hypothesis that the slope is equal to zero. Non-zero slopes indicate a significant impact of the predictor variable from the response variable, whereas zero slope indicates change in the predictor variable do ...

If X sometimes equals 0, the intercept is simply the expected value of Y at that value. In other words, it’s the mean of Y at one value of X. That’s meaningful. If X never equals 0, then the intercept has no intrinsic meaning.
