Representative data read from a plot on runoff sediment concentration for plots with varying amounts of grazing damage, measured by the percentage of bare ground in the plot, are given for steeply sloped plots.

Steeply Sloped Plots
Bare ground (%)	7	7	14	21	28	35	28	42	49	56	49
Concentration	120	300	360	720	600	600	1080	960	1320	1440	1200

(a) Using the data for steeply sloped plots, find the equation of the least-squares line for predicting y runoff sediment concentration using x = percentage of bare ground. (Give the answer to two decimal places.)

(b) What would you predict runoff sediment concentration to be for a steeply sloped plot with 16% bare ground? (Round your answer to the nearest whole number.)
