Identify What Is Wrong with Each of the Following Statements $800 \mathrm {~m}$

Identify what is wrong with each of the following statements:
a. The correlation between Olympic gold medal times for the $800 \mathrm {~m}$ hurdles and year is $- 0.66$ seconds per year.
b. The correlation between Olympic gold medal times for the $100 \mathrm {~m}$ dash and year is $- 1.37$ . c. Since the correlation between Olympic gold medal times for the $800 \mathrm {~m}$ hurdles and $100 \mathrm {~m}$ dash is $- 0.41$ , the correlation between times for the $100 \mathrm {~m}$ dash and the $800 \mathrm {~m}$ hurdles is $+ 0.41$ .
d. If we were to measure Olympic gold medal times for the $800 \mathrm {~m}$ hurdles in minutes instead of seconds, the correlation would be $- 0.66 / 60 = - 0.011$ .
