SCENARIO 11-8 An Important Factor in Selecting Database Software Is the Time

question 147

Short Answer

SCENARIO 11-8
An important factor in selecting database software is the time required for a user to learn how to use the system.To evaluate three potential brands (A,B and C)of database software,a company designed a test involving five different employees.To reduce variability due to differences among employees,each of the five employees is trained on each of the three different brands.The amount of time (in hours)needed to learn each of the three different brands is given below:
Below is the Excel output for the randomized block design:

-Referring to Scenario 11-8,what is the p-value of the test statistic for the randomized block F
test for the difference in the means?

Definitions:

Off Delay Cycle

A control or timing function where a signal or operation is delayed from turning off after an input trigger is removed.

MCR Instruction

Master Control Reset, an instruction used in programming PLCs to control the execution of a block of logic or instructions between its start and end points.

Nonretentive Outputs

Output signals or data in a control system that do not maintain their state after a power cycle or reset.

Latch Instruction

One-half of an instruction pair (the second instruction of the pair being the unlatch instruction) that emulates the latching action of a latching relay. The latch instruction for a programmable logic controller energizes a specified output point or internal coil until it is de-energized by a corresponding unlatch instruction.
