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:

This table displays the inventory of fasteners in a storage cabinet. An item is selected at random from the fastener cabinet. Find the approximate probability it is a bolt.

This is an example of part of a:

The primary metric for a project is reduced cost for process A. Baseline data might include:

Intuitively, which factor A or B seems most likely to be significant?

This table displays the inventory of fasteners in a storage cabinet. An item is selected at random from the fastener cabinet.

Find the approximate probability it is a 1/2 inch bolt.

The preferred method for determining statistically whether factor A or B is significant requires what additional information?

A team’s goal is to improve information flow in a payroll function. They make thirty-three Post-It® notes, each listing an issue for further investigation. After some discussion, they group them into four categories: mandated record keeping, privacy concerns, insurance concerns and transfer concerns.

This grouping process is best described by which approach to problem solving?

The principle disadvantage of fractional factorial experiments is that:

Find the value of (3) in the ANOVA table. Assume:
