When a cellular telephone user places a call, the carrier transmits the caller's voice as well as the voice of the person who is called. The encoded voices are the data of the call. In addition to transmitting the data, the carrier also stores metadata. The metadata of the call include information such as the time the call is placed and the phone numbers of both participants. For which of the following goals would it be more useful to computationally analyze the metadata instead of the data? To determine if a caller frequently uses a specific word To estimate the number of phone calls that will be placed next Monday between 10:30 A. M. and noon. To generate a list of criminal suspects when given the telephone number of a known criminal.

To estimate the number of phone calls that will be placed next Monday between 10:30 A. M. and noon.

Explanation:

Whenever someone makes a call from a cellular telephone, the carrier stores some data as well as some meta data.

The caller's voice and also the voice of the calling person are stored by the carrier as the data. The metadata are the information stored by the carrier are the phone numbers of both the participants and the time as well as the place of calling.

Thus for the following purpose, it is more useful to computationally analyze the metadata instead of the data since the metadata stores the time and phone numbers of the participants - --
