Question 1 1 pts A random selection of 10 chickens from Nebraska is used to test a new feed additive to see if the quantity used makes a difference in the number of eggs that the chickens lay per year. Quantity of additive mg 0 5 10 25 50 75 100 150 200 300 # of eggs layed per day 200 202 203 208 217 225 233 250 266 300 What is the parameter of interest? bi is the slope of the regression line between the amount of additive and the # of eggs layed for the sample of 10 Chickens from Nebraska. Of is the slope of the regression line between the amount of additive and the # of eggs layed for the sample of 10 Chickens from Nebraska. O bi is the slope of the regression line between the amount of additive and the # of eggs layed for all chickens in Nebraska is the slope of the regression line between the amount of additive and the # of eggs layed for all chickens in Nebraska
