A quality control supervisor wishes to determine whether the following measurements are random: $$\begin{array} { r r r r r r r r }
68.2 & 65 & 66.5 & 65 & 67.5 & 68 & 66 & 64.5 \
65.3 & 64.2 & 67.6 & 66.5 & 66.8 & 68.9 & 67 & 65 \\
& 65 & 67 & 68 & 71 & 68.5 & 63.6 & 64.7 \
& 71.5 & 70.7 & 66 & 68.5 & 70.5 & 69.5 & 70.1
\end{array}$$ For this purpose, the supervisor computes the median of previous observations, and finds it is 67.9.Then she compares each measurement to that median and assigns an "L" to it if it is below the median and a "U" if it is above the median.She determines that the number of Ls and Us are ______ and ______, respectively.
A)14; 16
B)17; 13
C)16; 14
D)18; 12
E)12; 18
