What is your blood type?

A-

O+

Here's the updated analysis.  Mathteacher, I counted you as O+ as Rh positive is more common than negative.

Type   Sample (n)      Sample (%)       Gen Pop (%)
A+         22                    25.3                   35.7
A-            9                    10.3                    6.3
B+           9                    10.3                    8.5
B-            6                     6.9                     1.5
O+         22                    25.3                   35.7
O-          12                    13.8                     6.6
AB+         4                      4.6                    3.4
AB-          3                     3.4                     0.6
 

Type Sample (n)      expected (n)       Difference
A+        22                    31                     -9
A-          9                      5                      4
B+         9                      7                      2
B-          6                      1                      5
O+       22                     31                    -9
O-        12                       6                     6
AB+       4                       3                     1
AB-        3                      1                      2
 

So far our sample has 10% fewer A+ people than we would expect, and 10% more O+ people than expected, about half as many O- people than expected, and 3 times as many AB- people as expected compared to the general population.

AB-         3                    1                       2

So far our little study shows that we have

4.5 times as many B+ women that we should have compared to the general population,

and twice as many 0- and AB+ women,

and almost 6 times as many AB- women.
