XmRdata
OBJECTIVE:
1. In an effort to stabilize the process, there was some discussion about "those 3 machines."These 3 machines have an 'apparent' effect on the material thickness (measured prior to plating). Prior to implementing the new process and procedures, the team wants to make sure that the three machines are not performing differently using a one-way ANOVA.You will be checking for 0.05 level of significance as to whether any of the machines significantly affect the means for material thickness.
2. What is the null Hypothesis?
3. What is the alternative Hypothesis?
