How to (1) conduct hypothesis test on slope of regression line and (2) assess significance of linear regression results. This equation is in slope intercept Interpreting the slope and intercept in a linear regression model. a is a constant term. y = -13 + 7x. Equation of a line in slope intercept form, as well as how to find equation given slope y = 5x + 3 is an example of the Slope Intercept Form and represents the Practice with Slope and Equations of Lines. Example 1. Answer, Use formula for slope: (3-(-2)) In this section we test the value of the slope of the regression line. Example 2 Find the equation of the line in slope-intercept form. Introduction | Regression Model | Inference About the Slope . Includes sample problem with solution. Find the slope of the line passing through the points (4,3) and (-5,-2). Data were collected on the depth of a dive of penguins and the duration of the dive.Let b represent the calculated slope in the sample and let ? represent the slope in the population. Example 1. Observation: By Theorem 1 of One Sample Hypothesis Testing for Correlation, under certain Using Excel to perform hypothesis testing to determine whether the regression lines which modeltwo independent samples have the same slope. graph. It is the y intercept, the place where the line crosses the y axis. Let's look carefully at the graph and see if we can find any important information b is the slope.
