A researcher is interested in the relationship between birth order and personality (outgoing versus reserved). A sample of n = 100 people is obtained, all of whom grew up in families as one of three children. Each person is given a personality test, and the researcher also records the person’s birth-order position (1st born, 2nd, or 3rd). The frequencies from this study are shown in the following table. On the basis of these data, can the researcher conclude that there is a significant relation between birth order and personality? Test at the .05 level of significance. 1st 2nd 3rd Outgoing 13 31 16 Reserved 17 19 4
