WebbChapter 14: Handout #2 Author: Catherine Schmitt-Sands, Ph.D. Application of Hypothesis Testing in Simple Linear Regression: T-test for significance The Regression Model, y = β 0 + β 1 x + ϵ, gives the relationship between x and y in the population. WebbP-Value is defined as the most important step to accept or reject a null hypothesis. Since it tests the null hypothesis that its coefficient turns out to be zero i.e. for a lower value of the p-value (<0.05) the null hypothesis can be rejected otherwise null hypothesis will hold.
WebbIn statistics, simple linear regression is a linear regression model with a single explanatory variable.

The Null and Alternate Hypothesis used in the case of linear regression, respectively, are: β1=0. β1≠0. Thus, if we reject the Null hypothesis, we can say that the coefficient β1 is not equal to zero and hence, is significant for the model.
