**Question 9: Use Common Sense in Gender Selection Trials** In a study testing a gender selection technique, 100 babies were born, of which 74 were girls. Is this outcome statistically significant? - (a) Yes. - (b) No. --- **Explanation:** The question asks whether the results of a gender selection technique, yielding 74 girls out of 100 births, are statistically significant. "Statistically significant" suggests that the observed outcome is unlikely to have occurred by random chance, assuming an even distribution ratio. Typically, without additional statistical analysis, one might rely on intuition or consider the usual birth ratio, which is roughly equal, to inform their choice.
