Please write it seriously and clearly 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? Laboratory 1: Tensile Testing The tensile test can provide...
