that is what the picture look like and it is asking-
What, if anything, is wrong with the frequency table for this data? 

34  21  54  44  33  17  22  56  78  62 
48  25  39  64  70  65  52  43  21  22 
46  28  39  76  63  39  42  55  29  30
  
   
 
  
 
  
 

 
 

  

  A. 
  The frequency table is correct.

  C. 
  The recorded frequency for the interval 40 - 49 is incorrect.

wouldnt it just be simpler to create a frequency table from the data to compare with?

amistre64 · Answer

or perhaps just dbl chk the 40s and 70s for comparison ...

amistre64 · Answer

i count 5 40s and 3 70s, so those are right;  B is just absurd since that is how one makes a freqTable ... so what does that leave?

Idk
