2) Construct 95% Confidence Intervals for the PERCENTAGE of
Aluminum ductility and Steel ductility. TREAT THE PERCENTAGE DATA
AS REGULAR DATA VALUES, AND NOT AS PROPORTIONS AS I SUGGESTED
EARLIER. What can you say about the typical proportion ductility
for Aluminum with respect to Steel? From a statistically
significant perspective, can you conclude the Aluminum ductility is
greater than Steel ductility based upon these CIs?
