Recent research has shown that women who skip breakfast are more likely to give birth to baby girls, whereas women who eat breakfast are more likely to have baby boys. To test this, we took a sample of pregnant women who already knew the gender of their baby and asked them how often they eat breakfast (every day, some days, or never). We want to analyse our data with a chi-square test. How would our analysis be described?

A. 3x2

B. 1x2

C. 3x3

D. 2x2
