Question 493799: 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+
A+
B+
O-
A-
AB+
B-
Type....Freq...Degrees
O+..... 6.......120
A+..... 6.......120
B+..... 2........40
O-..... 1........20
A-..... 1........20
AB+.... 1........20
B-..... 1........20
-----------add..360
do i add 360 to those numbers to get the degrees?
if not what is the percentage of total, and which is the degrees?
im confused.

You can put this solution on YOUR website! Type....Freq...Degrees
O+..... 6.......120
A+..... 6.......120
B+..... 2........40
O-..... 1........20
A-..... 1........20
AB+.... 1........20
B-..... 1........20
==========================
----add to get..360 degrees
do i add 360 to those numbers to get the degrees?
The 360 is just a check to see if the whole pie is filled
-----------
Draw a circle.
Sketch a central angle of 120 degrees; label the angle O+
----
Sketch a 120 degree central angle next to the one above: label it A+
----
Sketch a 40 degree central angle next to the one above: label it B+
Keep this up till you have filled the whole circle.
That is the pie chart you are looking for.
==============================================
