T R5.32. Wild horses Large herds of wild horses can become a prob- lem on some federal lands in the West. Researchers hoping to improve the management of these herds collected data to see if they could predict the number of foals that would be born based on the size of the current herd. Their attempt to model this herd growth is summarized in the output shown. 30 # of Fools 20 10 50 100 150 200 # of Adults 10 Residual (# of foals 0 -5 7.5 150 22.5 30.0 Predicted (# of foals)
