There shouldn't be a blood group difference between men and women as blood group type is not dependent on sex. However, you want to determine if this is true, so you go out and collect the following data on blood types:

Sex

Male Female

Blood type A 128 166

B 23 34

AB 14 19

O 131 163

Can you find a significant difference in blood types based on sex? Make sure you clearly state H0, H1, etc. Also clearly write out your decision and what it means.
