Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Number of bushels of wheat Choose the correct answer below. O A. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting zero point. OB. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. O C. The nominal level of measurement is most appropriate because the data cannot be ordered. O D. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point.

Liberty’s nose Is the Statue of Liberty’s nose too long?Her nose measures, 4′6′′, but she is a large statue, afterall. Her arm is 42 feet long. That means her arm is42>4.5 = 9.3 times as long as her nose. Is that areasonable ratio? Shown in the table are arm and noselengths of 18 girls in a Statistics class, and the ratio ofarm-to-nose length for each. a) Make an appropriate plot and describe the distributionof 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.
