$\displaystyle c=3.16(13)\times10^{8}$ m/s.
The actual value of $\displaystyle c$ =3.00x108 m/s is slightly outside of the error interval I have provided, but there is no reason why error intervals should include the actual value even if no significant systematic error exists because the actual value is barely outside this interval.
