Question

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-<50 60-90 Rel freg: 0.176 0.160 0.177 0.131 0.195 0.080 0.049 0.032 (a) Is it true that more than 50% of the sampled angles are smaller than 15, as asserted by researchers? Yes, the proportion of sampled angles smaller than 15° is greater than 0.50 Yes, the proportion of sampled angles smaller than 15° is not greater than 0.50. No, the proportion of sampled angles smaller than 15° is greater than 0.50. No, the proportion of sampled angles smaller than 15° is not greater than 0.50 (b) What proportion of the sampled angles are at least 30°? (Round your answer to three decimal places.) (c) Roughly what proportion of angles are between 10° and 25°? (Round your answer to three decimal places.) (d) Construct a histogram.

(Select all that apply.) There are two obvious outliers. Without more precise information, we cannot tell if the data contain outliers. The distribution of misorientation angles is approximately symmetric The distribution of misorientation angles is bimodal. The distribution of misorientation angles is heavily negatively skewed.
