question 74

Short Answer

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,is it appropriate to use the Tukey multiple comparison procedure based on the test result above?

Definitions:

Lithosphere

The rigid outer layer of the Earth, composed of the crust and the upper part of the mantle, which is divided into tectonic plates.

Continental Crust

The substantial section of the Earth's crust that creates the major continental areas, typically older and more intricate than the crust found beneath oceans.

Oceanic Crust

The thin layer of crust that forms the ocean floors, primarily composed of basalt and gabbro, and denser than continental crust.

Uppermost Mantle

The top layer of the Earth's mantle, directly beneath the Earth's crust, involved in tectonic plate movements and magma generation.
