• ○

  When the cutting speed increased from low to high level, the tool age increases

• ○

  The coefficient of the metal hardness is positively related to the output of tool age

• ○

  The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool age

• ○

  These plots prove a statistically significance factor with 95% confidence

• ○

  These plots are an example of interaction plots

• ○

  The dependent variable is the outside temperature

• ○

  The relationship between outside temperature and number of customers per hour is a Linear Regression

• ○

  The dashed lines indicate with 95% confidence where all of the process data should fall between

• ○

  The dashed lines indicate with 95% confidence the estimate for the Quadratic Regression Line

• ○

  The predicted number of customers per hour is close to 5 if the outside temperature is 10 deg C

• ○

  The initial focus for this project would be to determine why the thicknesses are so frequently too low.

• ○

  The majority of the process is closer to the lower specification limit.

• ○

  This process is described with the Weibull Distribution.

• ○

  The process has more problems with Variation than Centering.

• ○

  The process follows a non-normal distribution with the given data.
