Bell shape of student in a class has a height mean of 68 inches with 16% of them taller than 71 inches. What % of students are taller than 65 inches?
If the distribution is symmetric about the mean, then $P(h< \mu-3)=P(h>\mu+3)$. We're given that $P(h>\mu+3) =0.16$, so $P(h \geq \mu -3)=0.84$. However, the question asks for the percentage ...

Bell shape of student in a class has a height mean of 68 inches with 16% of them taller than 71 inches. What % of students are taller than 65 inches?
Or do we have to use Chebyshev's rule for finding k and then input in into mean-k*standard deviation=lower limit?
If you don't want the use of the symmetry of the distribution*
then we need something ...
