the questtion wording - Alice solves on average 7 puzzles per week is it ?

hartnn · Answer

anonymous · Answer

Im so sorry.  I left some information out. She can solve on average, 7 out of 10 puzzle.

hartnn · Answer

then i assume , 10 puzzles asked daily.
so on average 7 puzzles solved daily implies 7*6=42 per week 
and mean per week  =  42/ 7 = 6

anonymous · Answer

i think mean would be 7/10 x 6 = 4.2

anonymous · Answer

max puzzles she can solve = 6
min puzzles she can solve = 3
