Question

Statistics from the Port Authority of New York and New Jersey show that 84% of the vehicles using the Lincoln Tunnel that connects New York City and New Jersey use E-ZPass to pay the toll rather than stopping at a toll booth. Twelve cars are randomly selected.

a. How many of the 12 vehicles would you expect to use E-ZPass? (Round your answer to 4 decimal places.)

b. What is the mode of the distribution? What is the probability associated with the mode? (Round your answer to 4 decimal places.)

c. What is the probability eight or more of the sampled vehicles use E-ZPass? (Round your answer to 4 decimal places.)

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.
