Parking at a Large University Can Be Extremely Difficult at Times

question 78

Multiple Choice

Parking at a large university can be extremely difficult at times. One particular university is trying to determine the location of a new parking garage. As part of their research, officials are interested in estimating the average parking time of students from within the various colleges on campus. A survey of 338 College of Business (COBA) students yields the following descriptive information regarding the length of time (in minutes) it took them to find a parking spot. Note that the "Lo 95%" and "Up 95%" refer to the endpoints of the desired confidence interval.

$$\begin{array} { l c c c c c } \text { Variable } & \text { N } & \text { Lo 95\% CI } & \text { Mean } & \text { Up 95\% CI } & \text { SD } \\\text { Parking Time } & 338 & 9.1944 & 10.466 & 11.738 & 11.885\end{array}$$
Explain what the phrase "95% confident" means when working with a 95% confidence interval.

• A) In repeated sampling, 95% of the sample means will fall within the interval created.
• B) In repeated sampling, 95% of the population means will fall within the interval created.
• C) In repeated sampling, 95% of the intervals created will contain the population mean.
• D) 95% of the observations in the population will fall within the endpoints of the interval.
