Testing Effectiveness of Gender-Selection Technique The Chapter Problem describes the probability distribution for the number of girls x when 14 newborn babies are randomly selected. Assume that another clinical experiment involves 12 newborn babies.

Using the same format as Table 4-1, construct a table for the probability distribution that results from 12 births, then determine whether a gender-selection technique appears to be effective if there are 9 girls and 3 boys.
