Question

please answer to my question fast THE BEST ANSWER I WILL MARK THE BRAINLIEST ANSWER

Answer 1

Total marks for six tests=6*100=600
Now adding all marks of ayushree=68+75+70+45+57+77
=392
Now percentage score =392/600 * 100
=65.33%
Now for Ananya = 7*100
=700
Obtained marks = 52+87+64+53+74+81+86
=497
Now percentage score =497/700*100
=71%
Now for mean scores=Marks obtained/no of observation
For ayushree
=392/6
=65.33
For Ananya
=497/7
=71
Ananya has the higher mean score
Hope it helps
