An experiment was conducted on a new correlation of a particular make of pump to determine the flow rate discharge at different impeller speeds. The following data were recorded. Impeller Speed (rpm) 35 51 66 81 96 109 Discharge (m'/s) 17 26 42 62 89 119 (a) Fit a multiple regression curve of the form y = Bo + B1 x1 + B2 x? (b) Estimate the discharge when the impeller speed is 71 rpm.

WLEY 6-44. The data that follow are DC output from a windmill (y) and wind velocity (x). (a) Draw a scatter diagram of these data. What type of rela- tionship seems appropriate in relating y to x? (b) Fit a simple linear regression model to these data. (c) Test for significance of regression using a = 0.05. What conclusions can you draw? (d) Plot the residuals from the simple linear regression model versus y, and versus wind velocity x. What do you con- clude about model adequacy? (e) Based on the analysis, propose another model relating y to.x. Justify why this model seems reasonable. (f) Fit the regression model you have proposed in part (e).
