the mean of B is greater than the mean of A, in the case of a one-tailed test. Note that the second of these takes the form that it does because the sample mean for B was greater than the sample mean for A. Given the data above, you would never reject the one sided null hypothesis that the mean of B was greater than or equal to the mean of B.

Having first determined, from the hypothesis test of , that a statistically significant linear relationship exists between the dependent and independent variables, the strength of the linear relationship is measured by the coefficient of determination, . From its definition, R2 equals the proportion of the variation in Y explained by X.

The regression output has also produced the values of the t and F statistics (t=8.44, F=71.25). These values will now be used to test the null hypothesis that (1=0. The t value from the regression output has been found to be 8.44 (note that we use the value associated with the …
