What is the purpose of testing whether 8, = 0? O The purpose of testing whether 8, - 0 is to determine whether or not the mean of the x values is equal to the mean of the y values. O The purpose of testing whether 8, -0 is to determine whether or not the regression line provides a good fit for the data. O The purpose of testing whether 8, -0 is to determine whether or not there is a cause-and-effect relationship between x and y. O The purpose of testing whether 8, = 0 is to determine whether or not there is a significant relationship between x and y. If we reject 8, - 0, does it imply a good fit? O Rejecting 8, -0 does not necessarily imply a good fit. For example, if 8, - 0 is rejected and 2 is high, there is a statistically significant relationship between x and y but the fit is not very good. O Rejecting 8, = 0 always implies a good fit. If 8, = 0 is rejected, there is a statistically significant relationship between x and y which always implies a good fit. O Rejecting 8, = 0 never implies a good fit. If S, = 0 is rejected, there is not a statistically significant relationship between x and y which never implies a good fit. O Rejecting 8, - 0 does not necessarily imply a good fit. For example, if 8, - 0 is rejected and 2 is low, there is a statistically significant relationship between x and y but the fit is not very good.

What is the purpose of testing whether B, = 0? O The purpose of testing whether 8, = 0 is to determine whether or not the mean of the x values is equal to the mean of the y values. O The purpose of testing whether 8, = 0 is to determine whether or not the regression line provides a good fit for the data. O The purpose of testing whether 8, = 0 is to determine whether or not there is a cause-and-effect relationship between x and y. O The purpose of testing whether 8, = 0 is to determine whether or not there is a significant relationship between x and y. If we reject 8, = 0, does it imply a good fit? O Rejecting 8, = 0 does not necessarily imply a good fit. For example, if 8, = 0 is rejected and r2 is high, there is a statistically significant relationship between x and y but the fit is not very good. O Rejecting 8, = 0 always implies a good fit. If 8, = 0 is rejected, there is a statistically significant relationship between x and y which always implies a good fit. O Rejecting 8, = 0 never implies a good fit.
