TABLE IN THE ATTACHMENT

y= the thrust of a jet-turbine engine x1 = primary speed of rotation x2 = secondary speed of rotation x3 = fuel flow rate x4 = pressure x5 = exhaust temperature

x6 = ambient temperature at time of test.

1. Construct a normal probability plot of the residuals and interpret this graph.
2. Plot the residuals versus the fits (the estimated values of y). Are there any indications of inequality of variance or nonlinearity?
3. Plot the residuals versus x3. Is there any indication of nonlinearity?
4. Predict the thrust for an engine for which x1= 1950, x3 = 28900, x4 = 170, and x5 = 1589.
5. If you construct a 99% prediction interval for point estimate in part h would you expect it to be larger or smaller than a 95% prediction interval? Why? (No calculation is required.)
