Intuitively, which factor A or B seems most likely to be significant?
A random sample is selected from a population of measurements. The mean of the sample is not equal to the mean of the population. This is due to:
An engineer wants to try two hardening ovens to see whether they have different hardness scores. She cuts 8 pieces of bar stock in half, putting half of each in oven A and the other half in oven B. The following data are collected:
Do the data indicate that the ovens have different average scores? Assume differences are normally distributed.
An experiment has seven factors with two levels each. The experiment has eight runs. This experimental design is called:
This experimental design is an example of:
George is an employee of Black, Inc. John is George’s internal customer. Which statement is true?
The primary metric for a project is reduced cost for process A .A consequential metric could be:
A machine tool vender wants to sell an injection molding machine. The current machine produces 3.2% defectives. A sample of 1100 from the vender’s machine has 2.9% defective. Do these numbers indicate that the proposed machine has a lower rate of defectives?
A team wants a technique for obtaining a large number of possible reasons for excess variation in a dimension. They should use:
A team working with a plant relocation is tasked with designing a process for moving 180 pieces of equipment. Incoming orders may need to be filled during the move at either the old site or the new one. Transportation equipment availability is uncertain. Construction schedules at the new site is very weather dependent. The team designs a chart that attempts to cover these and other contingencies with appropriate measures dealing with each.
The tool best fitted for this task is:
