A researcher is interested in the relationship between birth order and personality. 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.

State the null hypothesis (1 point), the df (1 point), the critical value of chi-square (1 point), the expected frequencies
for each cell (you may just want to recreate the table; 6 points), the computed value of chi-square (2 points), and the
decision regarding significance (1 point).
