The latest results from a method of gender selection shows that among 152 sets of parents using the method for increasing the likelihood of a boy, 130 actually had boys and the other 22 had girls. Assuming that the method has no effect and that boys and girls are equally likely, a simulation of 152 births was conducted. The simulated number of boys and girls are shown on the right for 10 cases. Is it unusual to get 130 boys in 152 births? What does the result suggest about the method? Number of boys 86 82 60 69 68 77 90 91 78 74 Number of girls 66 70 92 83 84 75 62 61 74 78 Is it unusual to get 130 boys in 152 births? O No OYes
