The t-statistic is a measure of the significance of the relationship between the independent variable (X Variable 1) and the dependent variable (not specified in the given output). It measures the ratio of the estimated coefficient of the independent variable to its standard error. In this case, the t-statistic for X Variable 1 is 7.577, which indicates that the relationship between X Variable 1 and the dependent variable is statistically significant at a 95% confidence level.
