Multiple Choice

SCENARIO 11-10
A campus researcher wanted to investigate the factors that affect visitor travel time in a complex,multilevel building on campus.Specifically,he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building.Three subjects were assigned to each of the combinations of signs and starting locations,and travel time in seconds from beginning to destination was recorded.An Excel output of the appropriate analysis is given below:
ANOVA

-Referring to Scenario 11-10,the F test statistic for testing the interaction effect between the types of signs and the starting location is

• A)0.0109
• B)2.7844
• C)3.1742
• D)5.3176

Definitions:

Large-Sample Method

Statistical methods that rely on the theory of large numbers, allowing for approximation techniques when the sample size is sufficiently large.

Confidence Interval

A statistical range, based on sample data, within which a population parameter is estimated to lie with a certain level of confidence.

Number of Successes

In statistical experiments, the count of instances that meet a defined criterion for success.

Standard Error

A measure of the variability or dispersion of a sampling distribution, often used as an estimate of the accuracy of a sample mean.
