The bonding strength of an adhesive has been studied as a function of temperature (T) in C and pressure (P) as kg/cm. Data obtained are given. 30 74 Pressure 120 140 Temperature 168 90 30 138 104 90 58 96 Questions: 1. Establish the reduced statistical model after significance test (at 5% significance level) using Analysis of Variance (ANOVA). 2. What will be the bonding strength if temperature=65 and pressure=125? 3. Identify the optimal process setting for maximum bonding strength. 4. Establish the confidence interval of mean of bonding strength (at 95% confidence level)
