In a study of feeding behavior, zoologists recorded the number of grunts of a warthog feeding by a lake in the 15 minute period following the addition of food. The data showing the number of grunts and the age of the warthog (in days) are listed below. Find the equation of linear regression and interpret its slope.
y=-0.772x+210.8,s=210.8; Number of grunts increases by 210.8 per day
y=-0.772x+210.8,s=-0.789; Number of grunts increases by 0.772 per day
y=-0.772x+210.8,s=-0.772; Number of grunts decreases by 0.772 per day
y=-0.772x+210.8,r=-0.789; Number of grunts decreases by 210.8 per day
