Self-Esteem High Low First 74 26 100 Birth Second 56 19 75 Order Third 38 22 60 168 67 235 A researcher is interested in determining if there is an association between birth order and self-esteem. She collects data from participants who were either born first, second, or third in relation to their siblings. These participants complete a self- esteem questionnaire, and the researcher categorizes them as having high or low self-esteem based on the results. She then decides to test the association between these two variables. Using the collected (observed) data above and the expected frequencies (you will need to calculate them all - one for each cell in the matrix) and the chi-squared formula below, what is the calculated chi-squared value for this data? Round your answer to two decimal places. $$X^2 = \sum \frac{(f_o - f_e)^2}{f_e}$$
