At point E, the curve is increasing and concave down, which means the slope is positive but decreasing. Therefore, the slope of the tangent at E is positive.

At point F, the curve is decreasing and concave up, which means the slope is negative but increasing. Therefore, the slope of the tangent at F is negative.

Therefore, the correct statement is that the slope of the tangent at E is positive and the slope of the tangent at F is negative.
