Extracted text: 1. DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER What is the purpose of testing whether B, = 0? The purpose of testing whether B, = 0 is to determine whether or not there is a significant relationship between x and y. The purpose of testing whether ß, = 0 is to determine whether or not the regression line provides a good fit for the data. The purpose of testing whether ß, = 0 is to determine whether or not there is a cause-and-effect relationship between x and y. The purpose of testing whether B, = 0 is to determine whether or not the mean of the x values is equal to the mean of the y values. If we reject ß, = 0, does it imply a good fit? Rejecting B1 = 0 never implies a good fit. If ß, = 0 is rejected, there is not a statistically significant relationship between x and y which never implies a good fit. Rejecting B1 = 0 does not necessarily imply a good fit. For example, if ß, = 0 is rejected and r2 is high, there is a statistically significant relationship between x and y but the fit is not very дood. Rejecting B1 = 0 always implies a good fit. If ß1 = 0 is rejected, there is a statistically significant relationship between x and y which always implies a good fit. Rejecting B1 = 0 does not necessarily imply a good fit. For example, if ß, = 0 is rejected and r is low, there is a statistically significant relationship between x and y but the fit is not very good. Submit Answer O O O O
