Given:- A data set consisting of the number of girls and boys in different classes
To find :- The percentage of boys compared to the average number of girls per class
Formula used :- Average = \(\frac{total \ outcome}{total \ number\ of\ outcome}\)
Calculation :- Average number of girls in 5 classes = \(\frac{Total\ number\ of\ girls}{Number\ of\ sections}\)
⇒Average = \(\frac{25+20+25+32+24}{5}\) = \(\frac{126}{5}\)
⇒Average = 25.20
The percentage of boys in C5 compared to the average number of girls per class =\(\frac{Number\ of\ boys\ in\ C5}{Average\ number\ of\ girls}\times100\)
⇒The percentage of boys in C5 compared to the average number of girls per class % = \(\frac{26}{25.20}\times 100\)
⇒The percentage of boys in C5 compared to the average number of girls per class %= 103.17%
