A recent headline reads "Early Language Skills Reduce Preschool Tantrums, Study Finds," and the article offers a potential explanation for this: "Verbalizing their frustrations may help little ones cope." The article refers to a study that recorded the language skill level and the number of tantrums of a sample of preschoolers, and found that those with better early language skills had fewer tantrums. Assume that the sample used is representative of the population of all toddlers.
