Automated electron backscattered diffraction is now being used
in the study of fracture phenomena. The following information is on
misorientation angle (degrees).
(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.
Comment on any interesting features. (Select all that apply.)
The distribution of misorientation angles is heavily negatively
skewed.The distribution of misorientation angles is heavily
positively skewed.There are two obvious outliers.The distribution
of misorientation angles is approximately symmetric.Without more
precise information, we cannot tell if the data contain
outliers.The distribution of misorientation angles is bimodal.
