ASAAAP I WILL RATEE Two hundred and eighty boys completed a test that measures the distance that the subject can walk on a flat, hard surface in 6 minutes. For each age group shown in the table, the median distance walked by the boys in that age group is also given. Age Group Representative Age (Midpoint of Age Group) Median Six-Minute Walk Distance (meters) 3-5 4 545.3 6-8 7 585.0 9-11 10 666.3 12-15 13.5 700.1 16-18 17 726.6 (b) Find the equation of the least-squares line that describes the relationship between median distance walked in 6 minutes and representative age. (Round your values to four decimal places.) = (c) Calculate the five residuals. (Round your answers to three decimal places.) Representative Age (x) Residual 4 7 10 13.5 17
