Chapter 16 Question p. 738 #1 Consider the following data for two variables, x and y. x 22 24 26 30 35 40 y 12 21 33 35 40 36 a. Develop an estimated regression equation for the data of the form y = b0 + b1x b. Using the results from part (a), test for a significant relationship between x and y use = 0.05. c. Develop a scatter diagram for the data. Does the scatter diagram suggest an estimated regression equation of the form b0 + b1x + b2x2? Explain. d. Develop an estimated regression equation for the data of the form b0 + b1x + b2x2 . e. Refer to part (d). Is the relationship between x, x2, and y significant? Use = 0.05. f. Predict the value of y when x = 25
