Answer :
Answer:boys: median=50, mean=46
Girls: median= 33, mean=34
Step-by-step explanation:
Mean is the average. Median is the middle number. Both groups had 10 scores. Boys ranged from 15-81. Girls from 0-75; their mean & median would be less because their scores are less.

The mean and median of boys and girls should be 50, 46, and 33, 34.
Calculation of mean and median
For boys:
First we have to write in a sequence manner
15,18,22,32,50,50,55,56,81,81
So here the median should be 50
And, the mean should be [tex]= (15+ 18+ 22+ 32+ 50+ 50+ 55+ 56+ 81+ 81) \div 10[/tex]
= 46
For girls:
First we have to write in a sequence manner
0,7,12,22,25,41,43,45,70,75
So here the median should be [tex]= (25 + 41) \div 2[/tex] = 33
And, the mean should be [tex]= (0+ 7+ 12+ 22+ 25+ 41+ 43+ 45+ 70+ 75) \div 10[/tex]
= 34
