The correlation between the foot lengths of fathers and their (adult) sons, measured in inches, is r = 0.92. If fathers' foot lengths were measured in millimeters (1 inch = 25.4 millimeters), and sons' foot lengths were measured in furlongs (one furlong equals 7,920 inches), the correlation between foot lengths of fathers and sons would be:

a. much smaler that 0.92.

b. sightly smaler than 0.92

c. unchanged: equal to 0.92.

d. slightly larger than 0.92

e. much Larger that 0.92
