A quality-control apprentice is preparing a CUSUM chart. The values calculated for SL and SH are presented in the following table. Three of the values have been calculated incorrectly. Which are they?

\begin{matrix} \text{Sample} & \text{SL} & \text{SH}\\ \text{1} & \text{0} & \text{0}\\ \text{2} & \text{0} & \text{0}\\ \text{3} & \text{0} & \text{0}\\ \text{4} & \text{−1.3280} & \text{0}\\ \text{5} & \text{−1.4364} & \text{0}\\ \text{6} & \text{−2.0464} & \text{0}\\ \text{7} & \text{−1.6370} & \text{0}\\ \text{8} & \text{−0.8234} & \text{0.2767}\\ \text{9} & \text{−0.4528} & \text{0.1106}\\ \text{10} & \text{0} & \text{0.7836}\\ \text{11} & \text{0.2371} & \text{0.0097}\\ \text{12} & \text{0.7104} & \text{0}\\ \text{13} & \text{0} & \text{0.2775}\\ \text{14} & \text{0} & \text{0.5842}\\ \text{15} & \text{0} & \text{0.3750}\\ \text{16} & \text{0} & \text{0.4658}\\ \text{17} & \text{0} & \text{0.1866}\\ \text{18} & \text{0} & \text{0.3277}\\ \text{19} & \text{−0.2036} & \text{0}\\ \text{20} & \text{0} & \text{−0.7345}\\ \end{matrix}
