The p-value reported is for a two-tailed test that assesses whether the regression coefficient differs from zero. This is the standard test in regression analysis to determine whether there is a significant linear relationship between the dependent and independent variables. A two-tailed test assesses whether the coefficient is significantly different from zero in either direction, meaning that it could be either positive or negative.
