SCENARIO 11-12
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 11-12, the relative efficiency means that 1.0144 times as
many observations in each brand would be needed in a one-way ANOVA design as compared to
the randomized block design in order to obtain the same precision for comparison of the different
means.

Extracellular Fluid

Extracellular fluid refers to the body fluid lying outside the cells, which includes interstitial fluid, blood plasma, and cerebrospinal fluid, playing a crucial role in transporting nutrients, oxygen, and waste products.

Osmometric Thirst

The type of thirst triggered by the body's detection of high solute concentrations in the blood, often leading to the intake of water to dilute these concentrations and maintain osmotic balance.

Homeostatic Drinking

Drinking behavior motivated by the need to maintain body fluid balance.

Stakeholder Analysis
