question 171

Multiple Choice

TABLE 14-16
What are the factors that determine the acceleration time (in sec.) from 0 to 60 miles per hour of a car? Data on the following variables for 30 different vehicle models were collected:
Y (Accel Time) : Acceleration time in sec.
X₁ (Engine Size) : c.c.
X₂ (Sedan) : 1 if the vehicle model is a sedan and 0 otherwise
The regression results using acceleration time as the dependent variable and the remaining variables as the independent variables are presented below. The various residual plots are as shown below. The coefficient of partial determinations and are 0.3301,and 0.0594,respectively.
The coefficient of determination for the regression model using each of the 2 independent variables as the dependent variable and the other independent variable as independent variables ( ) are,respectively 0.0077,and 0.0077.
-Referring to Table 14-16,which of the following assumptions is most likely violated based on the normal probability plot?

• A)Linearity
• B)Normality
• C)Equal variance
• D)Independence

Respiratory Rate

The number of breaths a person takes per minute, a vital sign used to assess overall health and detect possible medical conditions.

Anatomical Dead Space

The portion of the respiratory system where air does not participate in gas exchange, including the trachea and bronchi.

Partial Pressure

Pressure exerted by a single gas in a mixture of gases.

Mixture of Gases
