Question 990181
<font face="Times New Roman" size="+2">


No way to tell.  Of the 90% who scored higher than 70%, 1/4 scored 90%.  That means that 3/4 of the 90% scored something different than 90%, but there is nothing to indicate what part of that 3/4 scored less than 90% and what part scored more than 90%.
