steps are not required, only the finally answer.
Metal Bonding Experiment.
Authors: E. Del Castillo, D. C. Montgomery and D. R. McCarville (1996), “Modified desirability functions for multiple response optimisation. Journal of Quality Technology, 28, pp. 337-345.
The experiment below is on a melting bonding process and was designed to determine the effect of the flow rate, the flow temperature and the block temperature on the maximum temperature recorded at the middle of the weld.

QUESTION 2 Calculate 97.5% confidence intervals for all the estimated parameters in the second order response surface model. Based on these intervals which one of the following statements is correct: Variable X2 is important in controlling the response but only via its interaction with variable X3 Variable X2 is important in controlling the response but only via its interaction with variable X1. Variable X2 is important, but its effect on the response is limited to being linear in nature. None of these options. Variable X2 is not important in controlling the response. Variable X2 is important, and its effect on the response is non linear in nature.Explanation / Answer
Question 1)
ans-> ii) variable X2 is important in controlling the response but only its interaction with variable X1
Question 2)
ans-> v) variable X2 is not important in controlling the response.
