Answer:
Yes, because the upper limit is less Than 8 minutes
Explanation:
According to the empirical formula :
68.26% of data lies within 1 standard deviation from the mean;
Hence,
Mean ± 1(standard deviation)
The sample mean and sample standard deviation of the given data is :
Sample mean, xbar = Σx / n = 546 / 100 = 5.46
Sample standard deviation, s = 2.475 (Calculator)
The interval which lies within 68.26% (1 standard deviation is) ;
Lower = (5.460 - 2.475) = 2.985
Upper = (5.460 + 2.475) = 7.935
(2.985 ; 7.935)
Since the interval falls within ; (2.985 ; 7.935) whose upper level is less than 8 means patients will have to wait less Than 8 minutes.
Beamforming can improve network service by using device locations to better target service signals.
This is because, beamforming helps to deliver higher signal quality to the target receiver.
<h3>What is beamforming?</h3>
beamforming can be regarded as application of different radiating elements that is transmitting the same signal.
This signal is usually identical in wavelength and phase, and by reinforcing the waves in a specific direction the goal can be acheived.

Answer:
A primary key is a special relational database table column (or combination of columns) designated to uniquely identify each table record. A primary key is used as a unique identifier to quickly parse data within the table. A table cannot have more than one primary key.
Primary Key.
Candidate Key.
Alternate Key.
Super Key.
Composite Key.
Foreign Key.
Unique Key.
In the relational model of databases, a primary key is a specific choice of a minimal set of attributes that uniquely specify a tuple in a relation. Informally, a primary key is "which attributes identify a record," and in simple cases constitute a single attribute: a unique ID.
