Suppose that the distribution of lifetimes of females in France is not symmetric. According to Chebyshev's Theorem, at least approximately what percentage of these lifetimes are within k=3.8 standard deviations of the mean?

93.7%  of the lifetimes  are within 3.8  standard deviations of the mean  

Step-by-step explanation:

   Generally Chebyshev's Theorem, can be mathematically represented as  

   %

The percentage  of these lifetimes that are within k=3.8 standard deviations of the mean is mathematically  evaluated using Chebyshev's Theorem as follows      

        %  % =  %

So from the above calculation we see that 93.7%  of the lifetimes  are within 3.8  standard deviations of the mean
