Range of ankle motion is a contributing factor to falls among the elderly. Suppose a team of researchers is studying how
compression hosiery, typical shoes, and medical shoes affect range of ankle motion.
In particular, note the variables Barefoot and Footwear2. Barefoot represents a subject's range of ankle motion (in degrees)
while barefoot, and Footwear2 represents their range of ankle motion (in degrees) while wearing medical shoes.
Use this data and your preferred software to calculate the equation of the least-squares linear regression line to predict a
subject's range of ankle motion while wearing medical shoes, ŷ, based on their range of ankle motion while barefoot, x Round,
your coefficients to two decimal places of precision.
