A workshop recorded, for several new trainees, the number of weeks each had worked, \(x\), and the number of units that trainee assembled per hour, \(y\). The recorded data are shown in the table.

Weeks worked, \(x\)	Units per hour, \(y\)
\(2\)	\(11\)
\(4\)	\(15\)
\(6\)	\(16\)
\(8\)	\(20\)

The line of best fit for the data is \(y = 1.5x + 8\). Based on this line, what is the predicted number of units per hour for a trainee who has worked \(12\) weeks?
