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,there is evidence of a significant difference in the mean amount of time needed to learn Brand B and Brand C at the 5% level of significance?
Auditory Pathway
The sequence of neural structures that sound waves travel through to be processed as sounds in the brain, from the ear to the auditory cortex.
