Suppose one estimates a linear model $$ y=\beta_0+\beta_1 x+\varepsilon $$ and finds that $\hat\beta_1>0$ and the $p$-value associated with $\hat\beta_1$ is lower than the chosen significance level. Can one say that
$\hat\beta$ is statistically significantly positive?
I am more used to the expression
$\hat\beta$ is positive and statistically significant.
Is there a difference in the meanings of the two expressions? Can one use them interchangeably?
