The slope coefficient
Weba researcher estimates that the value of the slope coefficient in a single explanatory variable linear regression model is equal to zero. which one of the following is most appropriate interpretation of this result? a. the mean of the Y variable is zero. b. the intercept of the regression is zero. c. the relation between X and Y is not linear. WebOct 4, 2024 · We use the following null and alternative hypothesis for this t-test: H0: β1 = 0 (the slope is equal to zero) HA: β1 ≠ 0 (the slope is not equal to zero) We then calculate the test statistic as follows: t = b / SEb where: b: coefficient estimate SEb: standard error of the coefficient estimate

WebInterpret the slope coefficient. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: In a simple linear regression, the following sample regression equation is obtained: y-hat = 436 ? 17x a. Interpret the slope coefficient. WebSlope is the change in y/change in x; the same thing as rise/run. Here is an example: Lets say you have a equation that says y=1/4x+2. Its pretty simple from there. So, we know in the …
WebHence, our slope will be same as the coefficient of x. The slope is 4. Example 2: The equation of a line is given as x = 5. Find the slope of the given line. Solution: The equation is given as x = 5. We can thus see that y is missing from our equation. Hence, we can assume the coefficient of y to be 0 for now.
