Question

A researcher wanted to study the commuting habits of community college students and faculty. He wanted to compare their mode of transportation to the college. He asked if they walk, bike, or drive to campus. The following table represents the data that was collected.

	Walks to campus	Bikes to campus	Drives to campus	Total
Students	70	22	78	170
Faculty	5	4	23	32
Total	75	26	101	202

A. Find the probability that a randomly selected member of faculty walks to campus.

B. If you are randomly selecting a person from those who bike to campus, what is the probability that you will select a student.

C. Perform a Test of Independence to determine if commuting habits are dependent on being a student or a faculty.

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
