Automated electron backscattered diffraction is now being used in the study of fracture phenomena. The following information is on misorientation angle (degrees).
Class: 0−<5 5−<10 10−<15 15−<20 20−<30 30−<40 40−<60 60−<90
Rel freq: 0.176 0.168 0.177 0.133 0.200 0.074 0.045 0.027

Is it true that more than 50% of the sampled angles are smaller than 15°, as asserted by researchers?

(A) Yes, the proportion of sampled angles smaller than 15° is greater than 0.50.
(B) Yes, the proportion of sampled angles smaller than 15° is not greater than 0.50.
(C) No, the proportion of sampled angles smaller than 15° is greater than 0.50.
(D) No, the proportion of sampled angles smaller than 15° is not greater than 0.50.
