To determine the half-life of a radioactive element, a student plots a graph of

\ln \left| {{{dN(t)} \over {dt}}} \right|

versus t. Here,

{{dN(t)} \over {dt}}

is the rate of radioactive decay at time t. If the number of radioactive nuclei of this element decreases by a factor of p after 4.16 years, the value of p is
