Answer 4

for comparing scores u have to calclulate the average score
of both classes

average score of first test of class


\(\large\tt \begin{align} \color{black}{
A_1=\dfrac{48+56+61+60+39+49+5+57+52+51}{10}\\~\\
=47.8\\~\\}\end{align}\)


score of first test of julia=\(\large 56\)


%scored higher than first test by julia


\(\large\tt \begin{align} \color{black}{=\dfrac{56-47.8}{47.8}\times 100\\~\\
=17.15 \%}\end{align}\)

average score of second test of class


\(\large\tt \begin{align} \color{black}{
A_2=\dfrac{75+81+63+74+59+88+77+79+76+69+67}{11}\\~\\
=73.45\\~\\}\end{align}\)


score of first test of julia=\(\large 74\)


%scored higher than first test by julia


\(\large\tt \begin{align} \color{black}{=\dfrac{74-73.45}{73.45}\times 100\\~\\
=0.74 \%}\end{align}\)

so she did \(\large worse\) on second test than first test
