1 What is the symbol for the change in the mean value of Y for each unit increase in X, assuming you are fitting the linear regression model Y = Bo + B. X 2. You want to build a linear model (Y = Be + B. * X) to predict a students grade (V) as a function of the number of hours (X) that student studied during the semester. Which graphical tool in statistics would you use to see if a linear model might be appropriate? Use for problems below: You are building a linear model (Y = Be + B. *X) to predict the pounds of corn (Y) you harvest per acre from your 100 acre farm given the number of pounds of fertilizer (X) you apply to each acre. You apply various amounts of fertilizer from 1 lb. to 5 lbs to individual 1 acre plots and then weigh the corn grown on that acre. Answer questions 3-9 below assuming the numbers in the Excel Regression Output are given below.
