Accessed 21 Sep 2022. This study aims to determine the description of entrepreneurship education and the application of the teaching factory as variable X, entrepreneurial competence as variable Y, and the influence of each variable x on variable y as well as its effect simultaneously (simultaneously). The simple linear regression model is y = 0 + 1 x + . If x and y are linearly related, we must have 1 # 0. The purpose of the t test is to see whether we can conclude that 1 # 0. We will use the sample data to test the following hypotheses about the parameter 1.
