SCENARIO 11-7
A student team in a business statistics course designed an experiment to investigate whether the brand of bubblegum used affected the size of bubbles they could blow.To reduce the person-to-person variability,the students decided to use a randomized block design using themselves as blocks.
Four brands of bubblegum were tested.A student chewed two pieces of a brand of gum and then blew a bubble,attempting to make it as big as possible.Another student measured the diameter of the bubble at its biggest point.The following table gives the diameters of the bubbles (in inches)for the 16 observations.
-Referring to Scenario 11-7,what is the value of the test statistic for the randomized block F test for the difference in the means?
Definitions:
Direct Labor Time Variance
The difference between the actual time taken to manufacture a product and the standard time expected, multiplied by the wage rate.
Direct Labor Time Variance
The difference between the estimated time for production and the actual time taken, multiplied by the wage rate.
Direct Labor Rate Variance
The difference between the actual cost of direct labor and the standard cost, indicating efficiency in labor usage.
Direct Labor Rate Variance
The difference between the actual labor cost incurred and the expected (or standard) labor cost for the actual production level.
