Question: A sample of 90 men and 110 women is asked about their handedness. A two-way table of observed counts follows:
Left Handed Right Handed Total
Men 11 79 90
Women 9 101 110
Total 20 180 200
a. Calculate a table of expected counts for these data.
b. Calculate the value of the chi-square statistic for testing the null hypothesis of no relationship between sex and handedness.
