for these Table S. Best-of-Fit Chi-Square Calculations for Sex Ratios. The observed numbers families can be found on this supplement page 6. Deviation (O-E/E Observed Expected 497 Deviatic Results O-E All boys 3 B:1G 2 B:2G 1B:3G All girls G99 Total e. Degrees of Freedom- d. Range of probability that deviations are due to chance- e. Accept or reject hypothesis? 5. Next, determine whether the overall ratio of boys to girls in the above data is consistent with the hypothesis of a 50:50 sex ratio. Remember that each family included in the table on page o consists of four children. In other words, to calculate the observed number of males, you must calculate the number of males in each family. For example, if 497 families have 4 boys, than those families contribute 1988 boys to the total for boys (497 x 4). These calculations were completed for you in the table. Calculate the x2 for these data by completing the following table. (1.5) a. What is the expected ratio of girls and boys? Table 6.
