Solution
Step 1
Write the data
162, 160,163, 160, 165,187,170, 167, 174, 176, 178, 179, 178.
Step 2:
Write the mean formula
[tex]\begin{gathered} Mean\text{ = }\frac{Sum\text{ of numbers}}{total\text{ number of numbers}} \\ Mean\text{ = }\frac{162+160+163+\text{ 160+ }\frac{\placeholder{⬚}}{\placeholder{⬚}}165+187+170+167+174+176+178+179+178.}{13} \\ Mean\text{ = }\frac{2199}{13} \\ Mean\text{ = 169.15} \end{gathered}[/tex]Mean = 169.15
