Multiple Choice

Refer to the figure.
Based on the information in the graph, what would you predict is the sound frequency (kHz) of ultrasonic bat calls?

• A) 3-kHz, because the intensity threshold is at its highest point and it is a low-frequency.
• B) 5-kHz, because the intensity threshold is at its lowest point and it is a low-frequency.
• C) 40-kHz, because there is a dip in the intensity threshold and it is a high-frequency.
• D) 100-kHz, because the intensity threshold is high, and it is the highest frequency recorded.

Definitions:

Probability

A numerical measure of the likelihood of a particular event occurring, expressed on a scale from 0 to 1.

Poisson Arrivals

A process that describes the probability of a given number of events happening in a fixed interval of time or space, assuming these events occur with a known constant mean rate and independently of the time since the last event.

Average Number

A value obtained by dividing the sum of all quantities in a dataset by the number of quantities in that dataset, commonly known as the mean.

FCFS

"First Come, First Served," a method of service in which requests are attended to in the order in which they are received.
