V. ERROR ANALYSIS
In an experiment, 10 trials were done to determine the range of a projectile. The measurements for the range of the projectile in centimeters are as follows:
\begin{tabular}{|l|l|l|l|l|}
\hline 134.8 & 133.9 & 135.1 & 134.7 & 135.3 \\
\hline 134.9 & 135.2 & 134.8 & 135.5 & 135.4 \\
\hline
\end{tabular}
Determine the (a) mean, (b) variance, (c) standard deviation, and (d) measured range of the projectile.
