The period of a pendulum is measured five times and the results $($in seconds$)$ are: $3\mathrm{.}5,3\mathrm{.}7,3\mathrm{.}1,2\mathrm{.}8,3\mathrm{.}4.$ The theoretical value is $3\mathrm{.}4$ seconds. Calculate the percent error and display the results in a table. $($Your data should consist of three numbers: theoretical value, experimental value, and percent error.$)$
