An 8th grade class develops a linear model that predicts the number of cheerios that fit on the circumference of a plate by using the diameter in inches.   Their model is Cheerios=0.56+ 5.11 (diameter)    a. Interpret the slope of your model in context.    b. What is the predicted number of cheerios for a plate with a diameter of 11?      c. The observed number of cheerios for a plate with a diameter of 11 inches is 51. Find the residual for a plate with a diameter of 11 and interpret its meaning.      d. Based on your residual from part c, was this an over- or underestimate?
