A statistical test or Hypothesis Test is performed to reject or fail to reject a stated hypothesis and it converts the Practical Problem into a Statistical Problem.
The Hardware Store ordered ten lawn mower from the manufacturer and just before shipping the manufacturer found one to have a motor that wouldn’t start. For the manufacturer this would be categorized as what type of cost?
Kanban establishes a means of monitoring production, conveyance and delivery information such that efficient flow is established. The method used by Kanban is to require a _________ before anything moves.
A ___________ is used primarily to track the stability of the average value of a metric of interest.
A Factorial Experiment based on a Level 2 Design with 4 factors would require 16 runs to fully assess the interactions.
When conducting a Hypothesis Test using Continuous Data the proper sample size is influenced only by the extent to which we need to assess a Difference to be detected but not the inherent variation in the process.
Which of these graphical presentations displays the values of each individual reading?
Upon completion and validation of an improvement to a process a Belt and the Project Team create a Control Plan that contains which of these?
The reported Cpk for a process with an average of 104 units, a spread of 18 units and upper and lower specification limits of 122 and 96 units would be?
The Control Limits width varies if the sample size varies for which type of chart?
When one speaks of 20% of something contributing 80% of the affect they are referring to what is known as the _________________.
Which of these might contribute to similar distributions having Unequal Variance?
A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt’s effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of $98 was estimated. The Alternative Hypothesis in the above example is?
Which of these are examples of business metrics or Key Performance Indicators commonly referred to as KPI’s?
A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt’s effort requiring that the average cost of an internal critical raw material component be less than or equal to $3,600 in order to stay within budget. Using a sample of 42 first article components, a Mean of the new product upgrade price of $3,200 and a Standard Deviation of $180 was estimated. Based on the data provided, the Z value for the data assuming a Normal Distribution is?
To establish a sample size that will allow the proper overlap of distributions we do which of these?
The Normal Distribution is considered to be the most important distribution in statistics and, among other things is defined as having a total area under the curve of 1, is mounded and symmetrical and the Mean, Median and Mode are _____________.

The class score distribution of schools in a metropolitan area is shown here along with an analysis output. Comment on the statistical significance between the Means of the two distributions. Select the most appropriate statement.
Use this data to calculate the Z Score. Average of: 92, Standard Deviation: 2, Upper Spec Limit: 101
