The owners of a new egg farm want to use the age of their hens (years) to predict the production of eggs (per year) using data collected from a sample of last year's hens. Assuming it is appropriate to use linear regression, answer all of the questions below using this table of sample data. Age (years) Eges (per year) 1 260 .80 270 40 285 15 .75 2.25 - 38 1.75 21401 Ch 12 Regression Table-Eggs-Age 54 .65 280 2 245 .89 265 Part A: What is the predictor/explanatory variable? Eggs (per year) Eggs x Age Age (years) Age + Eggs

Part B: What is the response/outcome variable? O Eggs (per year) Eggs x Age Age (years) Age + Eggs

Part C: Which of the following is the correct least squares regression line (i.e., line of best fit; regression equation) for the above sample data (table above)? Oj = 11.4629–.0391x Oy = 11.4629–.03912 y=.0391 - 11.4629. Oy = 291.1593 - 23.7472.c Oy = 25.1414 – 291. 15932 Oy= 23.7472 - 291.15932 y = 291.1593 – 23.74728 9 =.0391 – 11.46292 -

Part D: Which of the following is the value of the slope for the equation you selected above? O 11.4629 -291.1593 .0391 -23.7472 291.1593 23.7472 -0391 -11.4629

Part E: Which of the following is the value of the y-intercept for the equation you selected above? 0.0391 11.4629 23.7472 -291.1593 -23.7472 291.1593 -11.4629 O-0391

Part F: The value of the Coefficient of Determination you found for the above linear regression equation - (In the next blank space, type the correct numerical value rounded to 4 dec.; do NOT type the symbol or the = sign.) A/ The value of the Correlation Coefficient you found for the above linear regression equation - (In the next blank space, type the correct numerical value rounded to 4 dec; do NOT type the symbol or the sign.) The strength of this correlation is (Type the one correct word to fill in the blank: weak, moderate, strong.)
