Maud and Billy wanted to know if there's a difference between the modes of transportation used by men and women
One morning, they stood at the entrance to a big office building and surveyed people about the mode of
transportation they used to get to the office. Maud surveyed a random sample of 110 women and Billy surveyed
a random sample of 110 men. Here are the results:
Gender

They want to perform a x test of homogeneity on these results.
What is the expected count for the cell corresponding to women who walk?
