The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot. An analysis was completed and the computer output is shown. A graph titled Arm span versus foot length has arm span (centimeters) on the x-axis, and foot length (centimeters) on the y-axis. A line of best fit goes through (165, 23) and (185, 27).

Predictor Coef SE Coef t-ratio p
Constant -7.611 2.567 2.965 0.046
Arm span 0.186 0.035 5.377 0.000
S = 1.61 R-Sq = 63.0% R-Sq(Adj) = 62.7%
Using the computer output, what is the predicted foot length for a student with an arm span of 160 cm?
