A researcher is investigating the relationship between Foot Length (X) and Armspan (Y). He takes a sample of 3839 people, and makes the following measurements: . The sample mean of the foot lengths is 24.92cm. . The sample mean of the armspans is 170.07cm. . The sample standard deviation of the foot lengths is 2.51cm. . The sample standard deviation of the armspans is 12.59cm. . The correlation between temperatures foot length and armspan is 0.56. Using this data, calculate the LSR line for predicting armspan from foot length O a. y = 0.11x + 5.93 O b. y = 0.11x + 240.07 O c. y = 2.81x + 100.07 O d. y = 2.81x + 240.07 O e. y = 0.11x + 100.07
