question 48

Short Answer

TABLE 15-3
A chemist employed by a pharmaceutical firm has developed a muscle relaxant. She took a sample of 14 people suffering from extreme muscle constriction. She gave each a vial containing a dose (X) of the drug and recorded the time to relief (Y) measured in seconds for each. She fit a "centered" curvilinear model to this data. The results obtained by Microsoft Excel follow, where the dose (X) given has been "centered."

-Referring to Table 15-3, suppose the chemist decides to use a t test to determine if there is a significant difference between a linear model and a curvilinear model that includes a linear term. The p-value of the test statistic for the contribution of the curvilinear term is ________.

Definitions:

Voltage Change

A change in the electrical potential difference across a membrane, which can initiate an electrical signal or action potential in neurons and other excitable cells.

Fasciculi

Bundles of skeletal muscle fibers surrounded by connective tissue, contributing to the muscle structure and function.

Pennate

Describes muscles with fibers that are oriented at an angle to the tendon, resembling a feather's structure, which allows for higher force production.

Tendon

Band or cord of dense connective tissue that connects a muscle to a bone or another structure.
