The 95% confidence interval for a regression coefficient is the range of values that, with 95% certainty, contains the true value of the coefficient. The correct interval, (0.056, 0.218), suggests that the coefficient for the TO variable is significantly different from zero, indicating a meaningful relationship between the TO variable and the dependent variable within this range.
