Representative data read from a plot on runoff sediment conc

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.

Solution

a)

Using technology, we get              
              
slope =    13.73123123          
intercept =    41.93693694          
              
Thus, the regression line is              
              
y^ =    13.73123123x +   41.93693694 [ANSWER]

B)
              
Thus, if x =    19          
              
Then              
              
y^ =    302.8303303 = 303 [ANSWER]
