Question 493153:  this is my last problem i need help with. can someone please take a look.
 
6. Below are the blood types of 18 blood donors. 
  
O+    A+    B+    O+    AB+    
O-    B+    A+    A+    B-     
A-    O+    A+    O+    O+     
A+    A+    O+ 
  
i.     Make a frequency table using these 7 blood types: O+, O-, A+, A-, B+, B-, AB+ 
ii.     What is (are) the mode(s)? 
iii.     Does it make sense to talk about the average for this data? Why or why not? 
iv.     Using your frequency table draw a pie chart to display the distribution of blood types by filling in the following table: 
 Type |  Frequency | Percentage of total | Measure of Central Angle (in degrees) 
  
O+
