Question

Liberty’s nose Is the Statue of Liberty’s nose too long?
Her nose measures, 4′6′′, but she is a large statue, after
all. Her arm is 42 feet long. That means her arm is
42>4.5 = 9.3 times as long as her nose. Is that a
reasonable ratio? Shown in the table are arm and nose
lengths of 18 girls in a Statistics class, and the ratio of
arm-to-nose length for each.

a) Make an appropriate plot and describe the distribution
of the ratios.

b) Summarize the ratios numerically, choosing appropri-
ate measures of center and spread.

c) Is the ratio of 9.3 for the Statue of Liberty unrealisti-
cally low? Explain.
