We have to calculate the mean of this sample.
We can do this with the formula:
[tex]M_{}=\dfrac{1}{n}\sum ^n_{i=1}\, x_i[/tex]If we apply this to this sample we get:
[tex]\begin{gathered} M_{}=\dfrac{1}{16}(72+58+54+52+52+51+54+63+70+51+51+48+56+52+58+61) \\ M_{}=\dfrac{903}{16} \\ M=56.4375 \end{gathered}[/tex]Answer: the mean score is 56.4375.
