Explanation

Given height of six students= 144 cm, 158 cm, 172 cm, 160 cm, 132 cm, 182 cm

We know the formula,

 $\mathrm{Average} \left(\mathrm{A}\right)=\frac{\mathrm{Sum} \mathrm{of} \mathrm{given} \mathrm{values} \left(\mathrm{S}\right)}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{values} \left(\mathrm{N}\right)}$

 Here,

 Sum of given values(S)

=144+158+172+160+132+182

= 948

Total number of values(N)= 6

Substituting these values we get (A),

 $= \frac{948}{6}=158 \mathrm{cm}$

Hence, Option A is correct.
